This mod will add to the game stick, with which you can copy blocks and paste them to another location (if in your inventory enough material). Now it will be much easier to build big houses or palaces because you will be able to just copy the desired place - whether it is a wall, tower, a tree or a twig.
How to use the mod? To start straptite wand, then right-click on the desired location. Be allocated a large area. Now hold down the Shift key and prod the RMB to set the second extreme point. Now you have selected the desired structure. Press C to copy blocks and V to paste them.
