## Description
Instead of having multiple windows of the same application in the alt+tab dialog, have the ability to group all windows of the same application to a single icon. Ie. leafpad-file1, leafpad-file2, ristretto-image1, ristretto-image2, would simply be shown as leafpad and ristretto in alt+tab. This in conjunction with the already implemented feature to switch windows of the same application via a key binding would increase work flow for some users who do prefer such an interface.
