So I'll put in my own...
When I run Linux on a laptop, I tend to run Fluxbox, it uses a tiny ammount of screen real estate and is flexible snd nice to work with.
I am a bit sad that fluxbox won't be updated to wayland (at least not when I checked the last time), and I hope that waybox will be a good replacement.
Fluxbox... Now there's a name I haven't heard in a long time... Back in the days of wintel dialup modems I was trying out Linux as a teenager and trying to get modem support working to get the internet, and at one point I tried out a Linux distro, DSL (Damn small Linux) because it was set up to be installed and run from a USB flash drive with persistent storage on the drive I think. And the window manager of DSL? You guessed it, Fluxbox! Can't believe its still around.
Have you tried using the Fluxbox implementation version MX Linux makes available? They have put tons of work into their Fluxbox implementation. Perhaps it will provide you with some useful ideas/ help. Their Forums are also quite responsive & helpful. FWIW . I am not a paid announcer ;) ...
