> So in the open source community maybe, but it's use in the Android organization in Google is ubiquitous. Yes I know, I used to work on Android ;) > By split off, do you mean from a "branding" perspective? > And in practice, we've been working on the last year or so on "pluginizing" the UI - basically turning the UI into a modular set of components and separating the "core" of the UI (which doesn't know anything about Android or Chrome and reasons purely in terms of "tracks", "slices", "counters" etc). Yeah this is what I mean ^ > It's just that sometimes what we want to do for open source conflicts with what Google wants from us as a team in prioritisation. I actually talked about this in detail recently: https://lalitm.com/perfetto-oss-company-prio/ https://lalitm.com/perfetto-oss-company-prio/ Yeah this is basically exactly what I mean, in fact I am kind of impressed that you nailed it down so precisely. I actually ran into that very bug and saw it get resolved in real time. I think this is a really good sign. > So this is one reason Apple Instruments is so good at what it does: it's a focused profilier helping you debug problems on Apple devices and so they can deeply bake that intelligence in the tool. No I don't actually care about this part, I am mostly talking about usability for general workflows… > At least for this example, Perfetto has this feature: when zoomed out, click on a slice in an area you want to zoom to and then press "f". It wil snap zoom into that section …like this one. I learned about this shortcut but it doesn't actually work the way I like. "f" doesn't zoom far enough and it doesn't stack, so it will "focus" with the region as like a quarter of the screen. There's a bunch of other nitpicks I have, for example when I select a range it will immediately pop up the thing from the bottom that I invariably close until I actually want it, or that every time I open it the sidebar (that I never use) is open. Feature-wise, I still haven't figured out how I can do something like get an "activity view" (like the stack that shows how many tasks are active) across all tracks, or quickly select the region between two spans, or pin a whole process (rather than just a thread). I am sure that some of these are solved or I'm just holding it wrong but I feel like it's just harder to get what I want, especially since I can't really right-click anything which is what I typically do when looking for features. If it would help, I am of course happy to file bugs and also make simple fixes :)
