This is based on what was done using additional layouts, but modified to have a variable to control rotation and making it so Single Screen Layout behaves like Upright Single would, and Default Layout behaves like Upright Double would, when the new variable is used. Large Layout and Side Layout currently ignore the new variable. New variable still currently doesn't have a hotkey.
