have a pannel of the same elements on the left side which is the back layer and the right is the front layer
how to implament: to get to work you could have it so back layer stuff not collide with front layer stuff and the same with front layer not colliding with back layer stuff
what this could be used for: this could be used as background stuff or some electronics for the back and have some at the front. this would vastly incrase the amount of electronic stuff people can do :)
the problems that may happen with this: there is a couple of problems i could think of for it is that; fire could still set both on fire D: electronics would not be able to send electic to the other layer lag maybe? coding coliding issues with walls *the indurstruckable ones.
that concludes my idea i hope you take it into consideration
