MBP 15" user - 95% of my input to it is via the trackpad, I LOVE the 3-finger swipe navigation.
Saying "Swipe left/right/up/down" implies the end result of the movement, not the actual direction of my fingers. Swiping right means go to the window right of my current window. Swiping down displays all your windows/desktop background. Swiping up does nothing.
Really all I want, is to be able to swipe up to Spotify from any window or have a second set of windows on a level above the current, 1-dimensional horizontal window set.
Made a simple mockup as to what I am describing.
Is there already an app that allows things to work in this manner?
