Now we can save up to 3 custom map for the later use. How about removing this but add a system which will add options of export / import code of a map? So: in map creator player would be able only to make 1 or 2 short time saves just for the 'undo' / 'redo' and a buttons for import / export map into a code which we could copy and save in any file etc. In map choice menu just put import gap to paste any code we want.
