after about a month of using Scroll Reverser ( https://pilotmoon.com/scrollreverser/ ) i'm hooked. (hat tip: @gruber )

my brain has always thought of using a mousewheel and a touchpad gesture as two distinct types of interaction:

my mouse scroll wheel is manipulating the scroll thumb, which slides inversely to the movement of the content.

when i use a touch gesture to move something, i'm interacting with the content directly.

being able to separate these is awesome! tip sent to pilotmoon, well deserved.
