For harder ceramics like these a diamand coated bit (they aren't as expensive as the name makes the seem), always use water and drill through super slow so it doesn't crack (a minute or longer). Good luck!!

I either drill holes or for round ones put a smaller plastic draining pot inside

Yea I did something similar on GNOME I mapped one of my mouse side buttons to be META and that way I could use it to access the overview and applications aswell as using side button + scroll wheel to switch workspaces.

I love it so much I have implemented the same functionality In cosmic and would do the same in KDE.
