When creating lager maps, as for the current compition. I really lack a function for "copy" an area and move it. As for now you have to create all from start if you have to move something. It includes both terrain and entities.
I would love to see a funcion where you can draw an area with the mouse, mark it, and then be able to move it around.
I really think it would be a great option and save A LOT of time
