Different layouts for portrait and ladnscape

Idea: Ability to configure completely unrelated layouts for when the tablet is in portrait or landscape mode.

Background: Using camera streams means that rotating the tablet is not an option currently. However, I would love to be able to rotate the tablet for a different view.
Benefits:

  1. I could view the same widgets, but in a form which is usable for the aspect ratio
  2. Others might find it a quick way to change between the widgets they are interested in viewing
