Make normal dart shooters able to attach a certain block type to it and when you shoot the block it keeps going until it get in contact with a surface and it sticks to it, Making this would help builders build from far distances.

This would be nice if it worked. However, it is very easy to aim incorrectly and have a block appear somewhere where you didn't want it to.

If this was actually implemented, it would have to be so that wherever your cursor is pointing, that is where the block will be placed. No guesswork.
