I'm curious about what "decades of UX research" improvements you are talking about, to me everything about the UI for text editors or browsers hasn't improved much in decades. If you have a laptop with just a touchpad, chances are you'll never get better than vim keybindings. Moreover, the keyboard layouts themselves are centuries old.
> I'm curious about what "decades of UX research" improvements you are talking about Here's the most important one of them: Don't surprise me. Blend in. Look and behave like other programs. There are 50 applications on my system. Yours is one of them. If all other applications use 'Ctrl+C' for copying text, but your application uses 'y', then your application is the problem.
I don’t know about 50 applications. The rest of the applications I use are more specialized, and have their own shortcut madness. Browsers ate most of the small stuff.
