Can we have the refresh button a bit further away from the save button. Some times I accidentally mess up one of my creations, so then I go to refresh, but accidentally hit save then I have to fix the whole thing up again.
Click open save button. Click red and white box (containing a number 7) at bottom left of your save thumbnail. This will show all previous versions of the save (although the thumbnails are all the same, loading them will give the older versions).
