http://www.minecraftforum.net/topic...ks-v171-slopes-stairs-and-more/#entry22190438 Essentially makes blocks with slopes, stairs, gates, switches, buttons, pressure plates, etc that can be covered with any other block type to take on the appearance of the other block. and also be covered with snow, hay, cobwebs, grass or vines. I really like the way it looks and I think it would greatly expand building possibilities.
I could have sworn this was already requested once...oh well. We will consider it after the server has updated to 1.5 for a little bit of time.
