That may be, but I wasn't intending to say that AmigaOS beats out Linux - just that Linux UI is an unholy mess of warring standards applied with wild inconsistency to the extent that my two-week attempt to switch over last November left me wanting to kill people.
Yes, that might be even worse on linux (or unix-like systems, in general) than it's on Amiga.
And worse still, it's not only about different toolkits either, f.ex. Qt is now split to "classic" widgets and QML.
But in any case, sometimes it's really bad on Amiga too. f.ex. ReAction had some totally non-standard behavior for shift + cursor combinations, at least in text editor (select text instead of moving to the end)
