What lenses for Unity are available?
I'm looking for a lens that show the running windows and the other workspaces. Does it exisist? With this feature Unity can be like gnome-shell, I mean "one key to go": I press Super and I have all what I need.
No, there's no such thing, and that wouldn't be possible the way lenses work now.
I also don't really see why you would want to run it inside a lens. Think it would be better to simply add scale and workspace switcher to the corners and use them as they are, or use buttons on the launcher or something. That should be possible now, though you'd have to use less user friendly tools to configure it.
