@fsf my favorite program I use regularly is Emacs. I know it's already listed, but there really is no better editor in my opinion.

I even use my own configuration, because the distros of Emacs, just aren't very good for my needs. And now, because I use Emacs with a personal config, I will never ever be able to switch to a different IDE or editor.

@fsf Great question! For our community at ShirazLinux, Delta Chat and LibreOffice are everyday essentials.
