I have been using Linux Mint, before trying Manjaro. The option apt purge application_name was handy to remove all the leftovers along with uninstalling.
Leftovers like usr/share/icons/…, usr/share/docs/…, /etc/program/created/this, etc.
Here are my questions:
Is there an equivalent to apt purge?
Or,
Does removing from Add/Remove Software itself clean everything not leaving any leftovers?
