Ironically, the only[1] right-click option I used was changed into something more cumbersome: "open image" which was changed to "open image in new tab".
[1] I exaggerate a bit, sometimes I use uBlock Origin's "block element".
As a Swede, I've never seen or heard about pillows on desks :D
We do however have a law that workplaces must have some kind of resting area. In my former workplace we had a room with sofas, which sometimes people were napping in.
I use focus-follows-mouse (in fvwm), and the only app I can recall has any problem is Steam, in which the menus disappear if the mouse goes outside the steam window (or perhaps outside the menu, don't remember the details).
I actually didn't like (and still don't) Windows in any form, but the one thing I did/do like is the Windows 95/98/2000 UI. I came from an Amiga background, and even though I think of Amiga with fond memories, I thought the UI was a bit too spartan and clumsy (MUI was a step in the right direction though).
Nowadays I use Memphis-98 [0] as GUI theme (not desktop and window decorations). It's is kinda like Chicago95, but feels a bit more modern, not just a straight copy of Windows. There are some layout bugs, and some apps looks overall bad, like Firefox, Thunderbird and BDeaver. I had to manually turn off theming of DBeaver because it's basically useless with the Memphis theme.
I've started to use the new version 3 on desktop. But it still has got some problems when connecting/disconnecting monitors, so I use version 2 on the laptop where I need to do that.
No DE, unless you count LXQt as a basic session manager. I don't know why, but it seems things works more smoothly with a session manager instead of just starting fvwm from .xsession.
