Show HN: Kando – A cross-platform pie menu for your desktop
Kando is a cross-platform open source pie menu which I am currently developing! It offers an unconventional, fast, highly efficient, and fun way of interacting with your computer! You can use it to launch applications, simulate keyboard shortcuts, open files, and much more. Let me know what you think about it!
- klibertp 2y agoThe first thing I'd do would be to try to theme it with textures from Planescape: Torment... Joking aside, I've been hearing that radial menus are bad UX for decades, but I never understood why. For me, it was always much easier to build muscle memory with menus like that vs. traditional ones.
- philjackson 2y agoGreat docs and website!
- that_guy_iain 2y agoMy feedback is "Be precise" tagline seems wrong. It makes me think I need to aim at small dots instead of just going in a direction.
- Beijinger 2y ago"Kando is a cross-platform open source" This normally means it is slow. What does it do? It replaces my window manager? Or is an addition? I use the Moksha Desktop.
- DonHopkins 2y agoSimon, not only do you totally get the inherent advantages and joys of pie menus, and have the skills and persistence to implement them well and iterate on the design by continuously using and refining them over many years (at least a dozen years since you made trace and coral menus, right?), but you also have an impeccable sense of design and creativity, and they look really great! And the best part is that you've implemented an easy-to-use elegant wyziwyg drag-and-drop editor so anybody can edit and design their own pie menus, without writing json, xml, or code. Which is extremely important because everyone has their own personal use cases and important commands they need to select quickly. Thanks for all your work, and for making it open source, and going the extra mile to make it cross platform (which is extremely difficult)! I've written about how much I like your previous work before: https://news.ycombinator.com/item?id=17106453 https://news.ycombinator.com/item?id=17106453 DonHopkins on May 19, 2018 | parent | context | favorite | on: Pie Menus: A 30-Year Retrospective: Take a Look an... I'm very impressed by Simon Schneegans' work on Gnome-Pie: http://simmesimme.github.io/gnome-pie.html http://simmesimme.github.io/gnome-pie.html And especially his delightful thesis work: Trace-Menu: https://vimeo.com/51073078 https://vimeo.com/51073078 I really love how the little nubs preview the structure of the sub-menus, and how you can roll back to the parent menu because it reserves a slice in the sub-menu to go back, so you don't need to use another mouse button or shift key to browse the menus. Coral-Menu: https://vimeo.com/51072812 https://vimeo.com/51072812 That looks like a nice visual representation with a way to easily browse all around the tree, into and out of the submenus without clicking! I can't tell from the video if it's based on a click or a timeout. But it looks like it supports browsing and reselection and correcting errors pretty well! (That would be something interesting to measure!) There's another useful law related to Fitts's law that applies to situations like this, called Steering Law: https://en.wikipedia.org/wiki/Steering_law https://en.wikipedia.org/wiki/Steering_law The steering law in human–computer interaction and ergonomics is a predictive model of human movement that describes the time required to navigate, or steer, through a 2-dimensional tunnel. The tunnel can be thought of as a path or trajectory on a plane that has an associated thickness or width, where the width can vary along the tunnel. The goal of a steering task is to navigate from one end of the tunnel to the other as quickly as possible, without touching the boundaries of the tunnel. A real-world example that approximates this task is driving a car down a road that may have twists and turns, where the car must navigate the road as quickly as possible without touching the sides of the road. The steering law predicts both the instantaneous speed at which we may navigate the tunnel, and the total time required to navigate the entire tunnel. The steering law has been independently discovered and studied three times (Rashevsky, 1959; Drury, 1971; Accot and Zhai, 1997). Its most recent discovery has been within the human–computer interaction community, which has resulted in the most general mathematical formulation of the law. Also here's some interesting stuff about incompatibility with Wayland, and rewriting Gnome-Pie as an extension to the Gnome shell: http://simmesimme.github.io/news/2017/07/09/gnome-pie-071 http://simmesimme.github.io/news/2017/07/09/gnome-pie-071
- schneegans 2y agoHey Don, thanks for the kind words! And yes, with the latest updates we (and I can say "we" since various discord users collaborated on this) focused a lot on refining the "brand" of Kando. With the new website and the new logo, things are taking shape really nicely! I've written something about the new logo and icon here: https://ko-fi.com/post/A-New-Icon-for-Kando-X8X317HVLF https://ko-fi.com/post/A-New-Icon-for-Kando-X8X317HVLF I am really proud if it because it fits so nicely. The big next step will be to significantly improve the usability of the settings window. While the WYSIWYG editor is nice, it also has some issues which need to be fixed. It's always a full screen window (which is annoying) and it does not scale well to smaller screens.
- jimmySixDOF 2y agoHave you seen anyone port this to XR (VR/AR/MR) ? These radial menus are a good fit and a lot of designers work with them as a theme. Kando would be great in a library like Three.js or Babylon.js Here are two people experimenting with radials in XR: https://x.com/Volorf https://x.com/Volorf https://x.com/dmvrg https://x.com/dmvrg
- viraptor 2y agoAs much as I like the concept and it's a nice execution... It's an electron app. It's a 100+MB package that displays one widget. It runs a browser engine to displays icons on your screen. This is madness.
- schneegans 2y agoYou think so? I experimented with several toolkits. Some of my thoughts I wrote down here: https://github.com/orgs/kando-menu/discussions/58 https://github.com/orgs/kando-menu/discussions/58 I think there's a lot of unjustified prejudice against using web technology for desktop applications...
- viraptor 2y agoI wrote my own version of system-wide pie menu in swiftui in around 2 days (with no previous experience of swift), so I can say the tech/effort is not a limitation. On the other hand, the performance/resources can't be really analysed in isolation. There's too many apps that say "everyone can afford 100MB app and 250MB of ram, right?"... then that menu app and that tiny updater and that printer helper and slack and dicord and VPN app add up and we're at 3GB of ram usage already. (Yes yes, some of it can be reclaimed temporarily and then swapped back from files... but we shouldn't need to in the first place)
- v3ss0n 2y agoCute.. now let's see if it works on Linux, and then windows.
- viraptor 2y agoIt doesn't. The point is that for tiny apps it doesn't matter - you can replicate that interface in 3 toolkits very easily. Same applies to applications that want to display 3 edit boxes, an image and 2 buttons. Just do it in the native framework 3 times. It's not that much work.
- rickdg 2y agoTauri rewrite when
- schneegans 2y agoI tried using Tauri (would be very cool), but sadly they have severe performance issues on Linux which make an app like Kando impossible at the moment.
- danr4 2y agoIf you have a mac use charmstone.app I cannot go back to life without it.
- spondyl 2y agoAnother macOS native pie menu is https://www.pie-menu.com https://www.pie-menu.com
- Teever 2y agoI wonder what HN user Don Hopkins thinks about this.
- schneegans 2y agoHe replied already above :)
- v3ss0n 2y agoI would rather type.. smart auto completion or just fuzzy search + recency based run boxes are far superior than remembering gestures
- emacsen 2y agoI remember in the late 90s when there were so many alternative interfaces for PCs. It was a great time for exploration on what could be done. Kando is very pretty, and it can be fun to use an interface like this, but in terms of practicality, text inputs are better. For example, on my desktop, there's an icon on my taskbar for Firefox, but most of the time, I get my screen to the search bar and type "F" and my system knows I probably want Firefox. Done. There's a game I play, Astroneer, and it uses a pie interface. I often wish I could just type in what I want. It'd be faster. I want to love this, but I can type on a keyboard so much faster, and use up so much less cognitive energy doing so than switching my hand to the mouse, pulling up a menu, reading the symbols (even if I have their location memorized) and pulling my wrist/arm in the right direction.
- dingnuts 2y agoideally you have a button on your mouse to summon this, and use it when you are already using your mouse, and summon a different interface for typing from your keyboard, when your hands are there
- hju22_-3 2y agoI agree, but I also really like the pie menus. Personally, I'd like the ability to simply write to match, but otherwise working as demonstrated. E.g. like the Windows search works when you've hidden the search bar. I'd prefer both, in other words.
- snapplebobapple 2y agoRofi has that search to match but iant a pie menu
- schneegans 2y agoIf you have both hands at your keyboard, that's 100% true. However, it really works well with workflows which rely on mouse, stylus, touch, or controller input. Especially when used for "creative" or "artistic" tasks (e.g. painting, video editing, 3D modelling, etc.) pie menus can really have a benefit because you have your hand at the stylus or at the mouse most of the time anyways.
- TripleChecker 2y ago[flagged]
- schneegans 2y agoThanks for the typo pointers! It uses DOM elements. This makes it really easy to develop themes with CSS. I also did some experiments with alternatives to Electron, but found that the advantages of Electron clearly outweigh the disadvantages in this case. Here is some background information: https://github.com/orgs/kando-menu/discussions/58 https://github.com/orgs/kando-menu/discussions/58
- retrochameleon 2y agoThank you for addressing the Electron discussion thoroughly on Github. I am always very disappointed to see an application I am interested in using Electron. It is often enough of an issue for me to immediately write it off as something I will never use. I hope to see more Tauri instead, but you also addressed some minor issues about that option. I'll have to play around with this application.
- schneegans 2y agoYeah, Tauri would be great. But I think it will take quite some time until the fundamental rendering performance issues [1] under Linux can be fixed. There seem to be rough plans to bundle CEF on Linux [2], but AFAICS this seems to be only a discussion at this point.

- v3ss0n 2y agoIf they are bundling cef then it is rebuilding electron

- oulipo 2y agoReally cool! On osX BetterTouchTool can also do radial menus! Would there be a way to import/export a menu configuration from your tool as a .json?
- schneegans 2y agoThanks! All menus are actually stored in a JSON file. The format is documented here: https://kando.menu/config-files/ https://kando.menu/config-files/ So maybe it could be converted to different formats...
- oulipo 2y agoyes, I was thinking more of having a kind of "dotfile" approach to all my configs for automation on macOs, as there are so many different overlapping apps like BTT, KeyboardMaestro, skhd, Kando, Alfred, etc I'd love to have a `.automation` folder in my home where I can add descriptions of all my menus, keyboard shortcuts, scripts, Shortcut App scripts, BTT config, etc, and each time I modify them it updates in the app It would be nice to have a kind of overview of all my automations Also I'd like it that each file is some kind of "executable markdown" container which can contain textual description, images, etc, and the scripts/configs themselves, and the bindings Something like this -- name: emoji-picker author: xxx description: Various emoji-related bindings version: 1.0 url: xxx license: ... -- ```@deps ts: mdex>=1.0,<2.0 ``` ```@deps test // deps only for testing, etc ``` ```@include // can seamlessly include other .mdex, libs, code, repos, etc ``` # Open emoji picker The Raycast emoji finder is clean and easy to use, so I'll use it instead of the system picker ```@code ts openPicker const openPicker = async (prompt: string = "") => { api.url.open(`raycast://extensions/emoji?prompt={prompt}`); } ``` ```@test // define some code to run tests and ensure everything works ``` ## Trigger on `fn` key ```@binding key trigger: @on(platform == "darwin") key=[fn] action: code openPicker @(openPicker();) # equivalently, action: api open("raycast://...") ``` ## When called as a CLI, allow to pass an optional prompt to the emoji picker This installs an `emoji` cli, which parses with an optional prompt ```@binding cli name: emoji args: [prompt=""] action: code openPicker @(openPicker(prompt);) ``` ## Add custom bindings through extensions ```@binding ext:alfred keyword: emoji [query=""] action: code openPicker @(openPicker(query);) ``` ## Every hour, refresh the emojis ```@binding cron every: 1h action: code openPicker @(refreshEmojiData();) ``` ## Create an UI ```@binding ui name: emoji-ui layout: ... html: ... css: ... ``` ## Usage: ```sh mdex list emoji mdex info emoji-picker mdex install @user/emoji-picker mdex install emoji-picker.mdex # install or refresh script, install deps, setup key-bindings mdex test emoji-picker.mdex emoji "clown" # cli mdex uninstall emoji-picker # or trigger the `fn` shortcut mdex logs emoji-picker ```
- astrosloth 2y agoI am running RPi OS with GNOME 43.9 and was wondering if you have a release build for Arm (Pi 5)?
- woolion 2y agoIt looks a bit like the Krita right-click palette menu, which is made with a similar idea that you want to be fast while only access to a tablet stylus. I've seen that it has controller support, which is great; it's a cheap 'shortcut enabling' device that is readily available to most people. It would be a bit easier to have a video on the homepage that is a whirlwind tour of the program rather than the latest changelog. Although I have a motivation to find it useful (using a stylus restricts keyboard use), I've already set up a Tartarus with Input remapper to act as custom shortcuts etc, and it seems complicated to find how it would simplify or improve my existing setup.
