Firstly, love the mod, but I dearly miss the ability to interact with corner blocks. The mod that was suggested, Smarter Construction, does not help when I'm creating a mountain base with rock that's already there. This applies to smoothing too. I didn't find the option "grossly inefficient," but I found it extremely helpful. I dunno, I feel like it'd be better to just have it disabled by default, but allow users to enable it when they need to. Thanks for reading c:
