IIRC, there's a horrible work-around for the first item: hook up a magic mouse, invert the direction, and then plug in your mouse.

Since I don't have (nor plan to have) Magic mouse, that's kinda expensive solution :)

I use this instead: https://github.com/pilotmoon/Scroll-Reverser and it works well. Generally my preferred settings is like this: natural scrolling (ie. the mac default) for trackpad, but inversed (ie. linux/windows default) scrolling for mouse.

So if you connect a Magic Mouse and change the scrolling direction for the mouse it DOESN'T change the scrolling direction of the Trackpad?
