Request: gesture for adding tags.

[dscholtus]

Currently adding tags is a convoluted way to open the menu. But if you're working in fullscreen a gesture like a two finger swipe or a long press in a corner would be an excellent way to add tags. I foresee tags are going to be a game-changer for there remarkable device. In the cheat sheet for example a swipe up from the right down corner would be feasible..
