[Ayatana] Dash window buttons

[Roland Taylor <rolandixor@xxxxxxxxx>]

Shouldn't the Dash only use the close and maximize buttons?
IMHO the maximize button should invoke both resizing actions, 
eliminating the need for the minimize button (since the Dash cannot be 
minimized like a window). Apart from that, the minimize button incurs 
extra movement, and is also a bit confusing (I was confused by it myself 
and was clicking the maximize button to return the Dash to normal size).
