Helix text editor has been in my rotation recently, I like it a lot as a regular nvim user.

Just migrated from Arch to NixOS recently. Nix+Flakes+Home-manager define my entire system, including config files and pinned package versions, using three files. My system has never felt more stable and reproducible. I even found a flake which lets you declaratively manage Flatpaks (nix-flatpak).
