Super simple one. In the editor, sometimes I have wanted to place a tile underneath another one, but then I had reached the minimum height of the tiles. A button to move all of the tiles in the map up (and down) by 1 height would be super useful.
with copy-paste that will be possible in v0.6
Copy-pasting is coming 0.6 which will make this possible, but maybe it would still be good to have an easier way of moving the whole track
