The name Blocks Plus 2 Mod is enough to present its purpose. Yes, the mod mainly introduces many aesthetic blocks to the game such as cobblestone, smooth stone or stone bricks. Moreover, there are also secure blocks and phantom blocks which are compatible with servers in minds.
This mod is currently in Alpha for 1.7.2
This means that some features may not be working correctly or even present, I am working on making this mod stable and fit for a full release ASAP.
