Multitools and Special tools seem to need a bit of love...
-Mining any block with a multitool or special tool doesn't seem to decrease its durability?
-There is no way to define what types of tools a multitool mimics. Like, a pick+axe or a shovel+pick. Thus I usually use special tools instead, but;
-The Special tools' block selector is a bit archaic. There's no way to remove individual blocks (you can only remove all of them), and a way to "Add all blocks" and then remove the ones that I don't want would be much easier for me than the inverse.
