Hanging Sign Feedback

Firstly, I would like the hanging signs to have a full hitbox, you could make it so when they are hit by a hand, arrow, or otherwise a projectile, that they would swing like a bell. This would provide some interconnectivity between the player and the world they are in.

Secondly, when hanging signs are under another hanging sign, they should connect in 2 spots.

Thirdly, hanging signs on the side of a block should pop off if there is no proper support

Fourthly, hanging signs should be place-able and connected to fences, fence gates, and walls.
