Well after doing some research and trying VIM and EMACS for a bit. I already know that I don't want to use VIM over nano because the features I want neither of them has so it's pointless to even start learning using VIM and nano is sufficient for the basic stuff but EMACS does have the features. However EMACS is just too much... It's like I want to crop an image so I download Blender. The thing is too scary to even start with and needs so much customization just to get me started that I just don't have the energy to attempt it at once with NixOS.

So I've decided to pick up Helix again after all because it also has the features I'm after and needs very little setup to start learning to use it.
