Restricted Application added a project: Plasma.

REVISION SUMMARY
  preview button for themes, launches a fullscreen preview for the theme
  the preview image is shown as big as possible, either 1:1 or
  scaled down to screen size.
  
  clicking anywhere (or in the top right close button) dismissed the
  fullscreen dialog
  
  the thumbnail uses a plasma toolbutton, but in that particular point is fine
  to use a plasma control, because it's on top of an image, it's
  a custom graphics zone, where on the other hand a system style
  toolbutton wouldn't work well.
