Feature Request: Add the ability to change screen rotation.

[JamesKennewell]

Adding the ability to change screen rotation to have a Horizontal or portrait screen. This would allow for more customization in screen layouts

Changing the orientation between portrait and landscape seams to be feasible with low effort for the grid based tile screens.

Unfortunately the "non tile" screens (settings, color picker, key pad, ...) are optimized and hard coded for portrait layout. They would need a redesign that switches between the orientations.

Feels like a worthwhile feature if you are happy to implement it?
