Not sure if I really can or want to implement all of these things,
I've never liked sloped blocks because they are not really minecrafty.
Sloping blocks, may not be minecrafty, but it is there for "real world simulation".
It is just ok not to include sloping blocks since I just included it for "fun". Hehe...
Sloping blocks, FYI, is a reference to Carpenter's Mod, which I also use.
But what I really like to see is redstone integration. You do that and you have done other users of your mod a great favor.
