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.
Most Mac apps don’t have an uninstaller (or installer) you’re meant to just toss the app in the trash. The problem is this leaves in place your preferences files, any “application support” files it may have downloaded, maybe a cache, etc
That said, I’ve been migrating the same Library folder from Mac to Mac since around 2003 and have never used an app cleaner. It really isn’t an issue 99% of the time.
I can imagine a very edge use case for an app cleaner, but for most purposes - 99% of users - there’s really no reason for it. Macs don’t have a Registry. If you remove the application itself, all of its ancillary files in Application Support and elsewhere will just… not do anything. And they won’t interfere. They won’t interact in any way with anything else on your computer. And in most cases, they’re tiny files. There’s functionally no reason to care that they’re still around.
Sometimes there’s random startup files that clutter up the startup menu
