That's what I'm trying to do, have a very minimal interface and handle as much as possible with keyboard while still having a usable system with only the minimum necessary GUI. It's going to take a lot of unlearning/learning. I don't want to rely on pointer as much. And I get that this is not for everyone, I'm already test-driving Niro since it's closer to my Gnome work flow and may be a learning curve with a bit less friction that Hyprland or Swey.
I tried the last Cosmic, but found it lacks some of my wokflow parts, such as infinite auto-generated virtual desktops. Plus, Cosmic is still pointer first.
