The following two features would be useful.

1. The ability to select several fences and move them to another location on the desktop, keeping their position and size relative to each other.

2. The ability to click on a fence and cause the fence and its contents to appear in front of an open window. I suspect that this is not technically possible because of the way I think Fences works. Stardock is using a way to control the positioning of the icons on the desktop with a visual overlay of the fence. (i.e. the icons are not really in a fence like window that can be displayed altogether above another window)
