Adding two more indispensible ones for me:

Brightness Control https://www.splasm.com/brightnesscontrol/ The only macOS app that is actually able to properly dim my monitor beneath the lowest brightness setting without hacks like painting an overlay above your desktop such that it blinds my eyes when ever I switch workspaces.

Cursorcerer https://doomlaser.com/cursorcerer-hide-your-cursor-at-will/ Lets me bind a shortcut key to hide my cursor.
