For me these have entered into my must haves
- BetterDisplay: For better scaling support for external monitors
- Rectangle: To be able to use a mouse to drag and snap windows
- Pixea: To be able to double click an image with a mouse in any folder and then use arrow keys or scroll wheel to proceed to the next file in the folder. Replaced the stock preview with this.
Something I’m looking for now is the ability to use the forward and back buttons on my mouse when I’m in Finder and want to go back to the previous folder I was in. Doesn’t work in Safari either. Works in good old dependable Firefox though.
And separate volume controls for each applications.
BetterTouchTool (which isn’t free but is worth every penny) lets you do everything rectangle does. Also lets you configure your mouse buttons to do whatever you want. Also infinite custom hot keys and shortcuts.
Also Raycast as a replacement for Spotlight.
Raycast has replaced BetterTouchTool for me. I own a license for BTT, have it installed, but it’s never running anymore.
I installed an app to work around mouse scroll wheel acceleration, literally right after installing FF. I can’t recall the name though.
