The Launchpad page for the desktop-oriented version of Unity lists the following features separating it from the netbook version:
- A floating Unity Dash that can be moved to all edges of the screen
- Floating, overlapping windows with their title bars and controls on them, not on the top panel
- The home screen consolidated into a simple pop-down menu that extends down from the top left of the screen and allows you access to your programs and desktop search
I have some trouble picturing these, are there available mockups somewhere that could help us get an idea?
