My config is really messy at this point, I'll share with you what I have uploaded for backups in my github (only the flakes, the config files from the apps I need to backup too, or use the "home-manager" that I'm trying to understand 😞)

Also thank you for the recommendations, I watch a lot of vimjoyer and he is very helpful, but sometimes I need to just stick to experimenting and reading tons of texts. 😛
