Allow interaction with pinned windows by long pressing the menu button.
A quick press would still open dash, but a long press would just show your hands and allow interacting with pinned windows without bringing up the rest of dash/your belt.

Fantastic idea! I've felt the same restriction when you have a window pinned within a game and just need to interact with it super quick. A way to quickly enable/disable pinned-window interaction would be fantastic.
