Hi,
In Unity, one of the things I'm not very happy with, is the need on the same time to have two different ways of interaction:
1. The unity bar on left which is touch friendly
2. The menu bar (top bar) on the screen, which is better to be used with the mouse.
IMHO, sliding screen edges can be a solution to adding touch friendly interaction on top of regular interfaces.
A cute KDE guy has made a demo showing this and maybe it can be interesting to share here:
What do you think about adding such things in the future ?
