Some really good ones missed:
- iStat menu (better looking MenuMeters)
- Alfred (MUCH better spotlight)
- BetterTouchTools (keyboard, gesture, and other UX customization and macros, oh and window snapping with mouse and shortcuts)
I've been using Raycast [0] as an alternative to Spotlight and Alfred. Super fast file search, good looking and very extensible with its large community. Plus, it's a YC company :).
Paid version of alfred includes a clipboard manager and the ability to create workflows like add emojis or integrate with let’s say dash for documentation search etc. very nice, telepathy-like experience.
