You know how there are horizontal half blocks that will only sit on the ground, and that will hang off of walls on their sides? Well, I think there should be a vertical version of those that will set on the wall, and stand up on it's side on the ground. I know there are stone fences, but that just isn't really the same. Those will only go in the middle, and you don't really get to pick what side of the block you want to place it on. I've found times where a vertical half block would be handy! Is this a good idea?
