So the best thing about chisel (in my opinion) is how the blocks link together. I LOVE the cobblestone stuff, not just because it's cheap, but because it forms really cool patterns. I can have a layer where it all flows like one continuous path, to form a cool outline for the building. Really adds to the depth of the buildings.
Problem is, cobble is just about the only block that really does this! Is the newer version of Chisel doing this more with other blocks? I see loads of blocks that it "should" work for, but it just makes basic standalone blocks (the factory blocks are a good example). I would absolutely love it if there were more blocks that flowed together nicely.
