That’s a website, an app designed for iOS/OSX that had really bad dpi issues on Windows, a browser that tries to be its own OS and a program that’s actually notoriously bad UI-wise, to the point of using Flash-powered panels for whatever.
You know, unlike foobar, hammer, vlc, sharex, winrar, inkscape, notepad++, OBS, qbittorrent, everything, libreoffice, irfanview, handbrake, mp3tag, windirstat, mumble, hexchat, sumatrapdf, 7zip, gimp, grabber, paint.net a little, etc. (Also, no level editor or IDE uses the Ribbon.)
All I’m seeing is ex-SystemMenu users desperately playing dress up with their Quick Access bar. Sad!
Of course we wouldn’t need SystemMenu if we had a feature-complete replica that doesn’t introduce any new bugs living inside of the RibbonBar with no side effects, which by the way is exactly what I want. But we also wouldn’t need RibbonBar if we had a one living inside of SystemMenu. The real question is which of the THREE should be supported, my answer to that is the Legacy UI. After all, ribbon tabs are just less convenient palette windows you can’t undock.
