You might have some luck with a controller, using only a half of it, and re-mapping all controls there. Steam Controller might be great since it has touchpads. That might make some mouse-requiring games playable.

Using only keyboard, damn that’s difficult to find something, haha. I think these might work, just going by my memory: FTL, Toki Tori, Undertale, VVVVVV, Braid, Dome Keeper. Basically that kind of simple 2D games. Then almost any racing game.

You could also try some eye tracking solution, can’t help with that though.

This really needs a screen recording of it in action.

This is such a stupid minor thing, but it’s what made me switch from Ubuntu to Fedora, haha.

Fedora uses DNF, with rpms under the hood, not sure how that works, haha. Honestly I have no problems with it. I’m no power user, but it does everything I need. The only downside being kinda slow repo fetches.

I use many extensions, but I also like this “keep the vanilla simple” approach of Gnome. Instead of trying to support many different workflows, it does only one, and it does it well. Everything is much more polished, compared to other DEs, simply because there’s less stuff. And support for extensions seems to be excellent, since there’s so many of them and they often work very well.

Updating is not too bad, as long as you don’t update as soon as new major Gnome version is available. I usually wait a few months, and by then all extensions are either updated, replaced by a fork, or obsolete.

the only way I can think of to know which apps are in the background of that workspace is to memorize it

If you press Meta key and scroll, it shows all windows in each workspace. I think that’s also in vanilla, not one of my many extensions, haha.
