I would like in Unity, to see a preview of the open windows of a specific application. Just like Linux DockbarX (or windows 7).
Motivation example: When I have several windows open of the same browser, I would like to navigate to the correct one. Alt+Tab gives all the windows and not just the browser - is too much noise.
DockbarX gives the option to hover over the applications in the its launcher and it pops a preview of all open windows of that specific application.
How do I do this in Unity?
