I am sure this has been requested before but here goes. When working with Symmetry Plane on it would be nice if it also automatically deleted blocks from both sides as well instead of just working when a block is added. Would save a lot of time and trouble.
It already does. Just shift right click with a block in hand and it will delete the block you are looking at, and works in symmetry!
It would be better if just using the remove blocks function on the Multi Tool would do the same thing One of the problems with Shift Right clicking is the item is gone, but if you remove it with your MT it goes back into your inventory.
And therein lies my problem. Is there any way to do this in Survival? Seems like a pretty big oversight if not . . .
