Undo, Books, and Library Block

[the-arkhive]

I am absolutely loving this mod, and your others for that matter, they are all featuring heavily in a modpack/adventure map I am working on. As I have used it though I have found a few things I would really love to see. The first is an undo function. I realize this it's really how they work in Factorio, but I definitely makes mistakes trying to line everything up on the grid first try. That also relates to the second request, which I assume you are already working on, because this is based on Factorio. Books. Blueprint books would be so amazing. Maybe even a way to group the books by project or something. Which ties into the final request which is something like a library block, or really just any way to move blueprints between save files. A library system could be cool. One where all your saves can access the same list of books that have been added to it. I might also be making a PR with tile entity whitelist changes as I continue testing mods for my pack.
