Can you make it so we can place repeaters vertically? Also placing redstone/repeaters on ceiling would be also cool, especially for complicated circuits.
If you think you can add also colored redstone that doesn't interact with RS in other color (so you can't connect blackstone to green stone, etc.) with exception for whitestone which would be used when for some reason you need to connect RS in different colors.
Then call it Ultimate Redstone Mod.
Um Wow..... Well i am working on another mod but ill see what i can do.....
