Change section type/layout after editing
It would be great not to have to start all over by adding a new section when I want to change the section type. This might involve:
-- being able to switch the section type while keeping the content in tact
-- a button that swaps the layout of the section (gives me a couple extra options, as far as the ordering and sizing of items)
-- being able to easily copy and paste rich text from one box to another
