I've been hearing a surprising amount of positive feedback from people who have tried the current Gnome based DE on Pop OS. I haven't tried it myself, but I've heard that they have some sort of tiling / snapping that works well. I'd like to try it, but I'm heavily invested in upstream Debian and am not really interested in installing another Debian derivative. Are there plans to package this up?
I'm currently using XFCE on two computers with key bindings for snap left/right and snap top-left/top-right/bottom-left/bottom-right. On a big display, this setup is excellent. On a laptop it works, but often feels a little cramped, and it's particularly painful with a laptop trackpad instead of a mouse. It would be nice if there was an option to split ~67%/33%... apparently Windows(!) can do that.
I've also been playing with i3 on another laptop, and for a lot of things the experience is clearly better (e.g. web browsing on a laptop without a mouse), but for others (e.g. kicad) it either doesn't work well, or I haven't managed to configure it well enough yet. The rabbit hole is infinitely deep, and while I enjoy tinkering with it every now and then, I'm probably not going to use it as a daily driver anytime soon.
I've been using it for a year and love it--typing this reply in a browser window tiled next to a terminal. It's easy to add little exceptions too for modal apps you want to hover outside the tiling.
