Multi platform is an awesome quality for a tool like that: when you do have a customization like that, it's a huge value-loss when it can't be passed on across system boundaries. That being said, this appears to be an active mapper that needs to be running in the background. Classic "with great power comes great responsibility". I'd rather have something less powerful that only offers the customizations that can be loaded into the native keyboard mapping engines. On Windows, I am extremely happy with a few tweaks I've built with Microsoft Keyboard Layout Creator (MSKLC). Mostly removing some of the worst pain points of my home language layout (German) that drive many of my compatriots to using an English layout (basically what nodeadkeys does on Linux, but with a few improvements like opting in to dead keys behavior with altgr+’). Would be super awesome to have a UI for setting up that kind of mapping that can output configurations for the native mapping mechanism across a range of platforms. And that only offers mappings that can be configured using the native system on all platforms supported, the intersection of capabilities.
