Make it so that you can configure distance where the block is being placed. I think it would be useful not having only 6 block distance

Or maybe be able to configure it when you run the /airplace command like /airplace <reach: default = 6>

I am currently working on the airplace feature already so I could implement this

or you could shift+scroll the distance

Yeah or have like a command /airplace incrementreach and allow people to bind it to keys with macros

or we just make the player's reach configurable in general, not just for airplace

This'll be implemented by #80
