scc is an insanely fast alternative to cloc: https://github.com/boyter/scc

nnn is also my go to file tree navigation / file moving tool these days too: https://github.com/jarun/nnn

For counting coding lines I use tokei and I like it: https://github.com/XAMPPRocky/tokei

https://github.com/kamiyaa/joshuto in favor of nnn.

No file previews yet? I'd stick with ranger or lf.

It makes you feel less painful reading man pages with bat being the colorized pager.

This snipper in my ~/.profile colorizes man pages for like ten years already:

  #   Colorify man (changes default $MANPAGER (less) settings)
  export LESS_TERMCAP_mb='^[[01;31m'
  export LESS_TERMCAP_md='^[[01;31m'
  export LESS_TERMCAP_me='^[[0m'
  export LESS_TERMCAP_se='^[[0m'
  export LESS_TERMCAP_so='^[[01;44;33m'
  export LESS_TERMCAP_ue='^[[0m'
  export LESS_TERMCAP_us='^[[01;32m'
