[Arindam Kawlas]

Is your feature request related to a problem? Please describe.

The theme currently has very limited support for many different programs.

Describe the solution you'd like

Themer by @mjswensen can be used to add support for a lot of them within a few minutes.

Additional context

Support all the colorscheme variants as well (especially, carbonfox)
Maybe try base16 as well
