What are some must-have programs in your opinion?

Howdy all just looking to see if I missed anything or could be introduced to something new!

For me my must-haves are:
Flameshot
Discord
Blueman with required bluetooth shit
XFCE 4
Plex Desktop
Blackarch Repo

Firefox

Is there anything else that you love and can't live without on your system and/or that I should add to mine?!

Cheers!
