I don't know if this has been suggested before, but here goes. I would like to see a few features in the tilemap object to make editing it easier. For one it'd be cool to see a selection tool that allows you to drag tiles around to another location and possibly cut and paste them. And an option to shift tiles up, down, left or right would be nice too because as it is, as far as I know, you have to just draw everything all over again if you're using one big tilemap object if you didn't give yourself enough room on the left for example and need to shift everything over.
