would be handy if the drag and drop function would only be able to become as big as you got blocks on your stack, now when making big surfaces the mirrored side only gets half filled in because you run out of blocks oh I cant fill this whole area, lets grab some more blocks.. in stead of; ah dang I didnt have enough blocks, now I need to reposition and do it again
I haven't made use of "mirror" yet. Mainly because I have had trouble making it work. I really need to ttake a another stab at it.
