Well, I surprised myself by making it through the first video, at least. It was interesting to hear the guy ripping on the "hide the menus" concept as hard as I've always done. That shit drove me berserk when it came out.

Old word for macOS had the best UI in my opinion, it was like Photoshop, where the functions where in a separate floating window on the side.

That makes totally sense, since word is normally used with paper being portraits oriented while screens a normally landscaped.
Gives much more screen estate and doesn’t reduce hight which is limited anyway.
