I use NixOS+GNOME+pop-shell for tiling windows on Linux, and I love it!
I am quite frequently on MacOS, and I use Yabai[0] and skhd[1], managed with Nix-Darwin[2] for tiling windows and custom keyboard shortcuts. With how I make my Linux and MacOS builds look and feel identical it's pretty easy for me to forget when I'm on one vs the other.
For anyone curious, here's my repository for deploying my configs[3]. It's awesome to have one source of truth for managing NixOS servers and workstations, MacOS workstations, and other Linux workstations with Nix installed.
