Red is aware of the issue where you can't place two ramp blocks next to each other nor stack up half-blocks because they are still blocks and therefor cannot occupy the same block space. He's working on correcting this and also introducing scale-able blocks. I'm presuming this will all come out with the advanced crafting update and will likely involve converting blocks to scale-able and freely rotatable objects which will be free from the block grid limitations.
If that is the case perhaps some of this conversation is not relevant if stone blocks end up like beams / planks.
I dislike you can't view planks / beams fully as you place them, and the fact they go through solid walls and flicker.
