Pretty simple suggestion: Just a way to turn any block, wedge, corner, tetra, or penta into any one of the other available shapes for that block. Currently once you 'cut' a block into a shape it's stuck in that shape, which is annoying; it should be possible to take any shape-type of block that you get and turn it into a different one. The old factory system could do this, and I see no good reason why this system shouldn't be able to. I keep running into issues where I have too many wedges and not enough regular blocks, or pirates drop a giant stack of pentas, or corners that I can't really use, and I really need to make most of them into blocks. :\
...At the very least, there should be a factory that turns tetras, pentas, corners, and wedges back into full blocks.
