If you launch the Unity Dashboard, there are the traditional 3 buttons in the top-left-hand corner. They look (something) like this:
X ― □
The X closes the dash.
The □ either maximizes or minimizes the dash, depending on it's current state.
The ― does..
I know it's faded out, but couldn't it have the same function as close, or almost the same but have the dash fold into the top-left-hand corner?
Note: I always have my dash maximized, so to me they are the close, minimize and minimize button. Please use the symbols, so i know which one you mean.
