I mean I use rectangle, and used spectacle before it, and I’m very grateful to the developers for maintaining it and making it available for free, but this really should be part of the OS and I will be very happy to get rid of that app after updating to Sequoia.
I also use an app that reverses the scroll direction of an attached USB mouse, without affecting the (natural) trackpad scroll direction, because MacOS does not allow changing them independently (looks like they are separate options for mouse and trackpad but they are in fact the same).
The App is called Scroll Reverser [1] it is free and works flawlessly, but it really should not have to exist, it’s ridiculous.
