You know how it feels like being lost in lots of windows on your Ambient and the need to rearrange them one by one to be able to simply click an icon hidden behind all that mess. Here is the cure to this annoyance.

- The number of hidden windows in the information window is now updated when a window is made visible again via the context menu. Also the corresponding entry in the context menu gets removed.
- The information window now has a context menu which contains all hidden windows.
- If started a second time the first unmask instance won't quit anylonger but will open its prefs instead.
- Now preserves the depth arrangement of the windows when reshowing them.
- Window count of hidden windows wasn't accurate. Fixed.
