It would be cool if the colorscheme file was just a config file so we don't need to recompile gotop in order to create our own themes.

Hmm that's a good idea. Maybe have a config file at ~/.config/gotop/config or something. But also keep the built in colorschemes and still enable them with the flag option I think.

Yep was thinking like that!
