hey Mike, some notes from me:
I've been playing around with your mass cleaner, and noticed that it doesn't work when pointing at a block above you. So I can't clear upwards, only forward and downward. Don't know if that is intended but it seems more like a bug.
Also, graphene plates recipe just doesn't show up in NEI, is it because that NEI plugins mod doesn't support your mod yet? Actually, NEI doesn't show up any of your recipes except 'shaped' recipes. Also, when your play with flat bedrock feature/mod, there seems to be no way to actually start to work with your mod. I'm using that feature from TE (I think), so my bedrock is flat, so I can't break it and I can't craft any of your machines.
Also, the leaf blower seems to clear also the tree leaves, which is a problem when you use treecapitator. By deafult, Treecapitator recognizes trees with checking if there are some leaves attached, that is to prevent accidental mass destruction off wooden constructions. That conflicts with your mod, since when you use the blower, leaves are gone and you can't chop down those trees quickly anymore, because Treecapitator thinks that they are no more tress. Adding a config for which blocks should be blown away would solve it.
This addon is very nice, a lot of great ideas in it. Leaf blower is great actually
Thanks for your work, and keep it up
