I use Lazygit, which is a TUI. It is entirely controlled by keyboard shortcuts and has a lot of quick ways to do tedious things.

Important to note that NixOS has both a rolling release and point release version.

The generic keys have been known for a very long time. I highly doubt it means you’ll get anything else out of them.

Oatmilk is easily the best alternative imo. It can be frothed pretty well too.
