Disable/hide visual borders when hovered over, atleast in full screen mode. It makes the UI look pretty untidy.
Worst thing is the empty bar on top of every visual consumes so much of real estate! It has no real purpose other than making the report look ugly on mouse hover and consuming lot of space. This could atleast work like a Windows Title bar where you have the Window Title, Close, Minimize and Maximize button. Qlikview uses the title bar efficiently.
