This is CornerAmp 1.4 being updated for Winamp 5.6x. Right-clicking on the CornerAmp label in the main window, allows you to select a corner. But the position is not remembered. Why? How can you make the skin remember where you put it last?
CornerAmp 1.5 remembers the positions but it does not auto-snap into the corners and it does not have the jump-to-corner menu either.
