I would add:
cheat
- a tool that lets you make and use your own cheatsheets
gomi
- replacement for the rm
command that has a trashcan, so if you accidentally delete something important you can just restore it
bat
- modern cat
, with features like syntax highlighting, line numbers, etc
eza
- modern ls
, with cool features like file icons
broot
- a different than ranger
/lf
approach to navigating folders
mdr
- a markdown viewer
Also, I think you should add a note that ranger
should be installed from git because most distros package version 1.9.3 and that is 4 year out of date and has lots of bugs that have been fixed in the git master branch
Not really surprising considering that (IIRC) it’s the default on the Gnome variants of Ubuntu, Debian and Fedora
But keep in mind that voluntary data tends to be pretty skewed
