These 2 apps are often used together, so why not merge them together?

That's actually pretty awesome. I wasn't aware of this problem or this solution, but I recently bought a Logitech MX Master 2S to test with Scroll Reverser and now I understand what the scroll wheel problem is! Thanks for suggesting this.

horizontal scroll (shift+scroll) is not affected

Awesome feedback, thank you. This also ties in with #31.

I didn't include Horizontal because I didn't know of any mouse with horizontal stepper scroll wheel. But this makes perfect sense. (I'm actually not familiar with using scroll wheels, I've always used a Magic Mouse. But recently been using a Logitech MX Master 2S specifically for Scroll Reverser dogfooding.)

Note to self: Seems TextEdit is a good representative app for this shift+scroll behaviour.
