A little mockup of an idea I had for single-input app switching mechanism.
The concept is to allow for instantaneous app switching, via a simple swipe up from the bottom (splitting the screen). Without lifting your finger/thumb, you swipe to one of your recently used apps, release, and jump into it in one swoop.
Just an idea I had to get out of my system tonight, will try to make a video later!
