When 'show iconified windows' is on, show thumb

Suggestion: in options, when 'show iconified windows' is on, add:

1. make a snapshot (thumb) of the minimized window and use it as icon (toggle)
2. show only iconified windows of current workspace (toggle) (done in ROX-Filer 2.3)

I like that idea. They would help the user have a better idea of what the minimized folder was, and it would help disinguish more clearly the fact that the minimized program in question is, in fact, a minimized program and not a shortcut. --James Gecko
