Requires the library mod Collective.

Better Beacon Placement is a minimalistic configurable mod which allows player to easily place beacon bases by right-clicking the beacon with a mineral block. Sneak/crouch+right-clicking places the entire stack in hand. Breaking the beacon will also break all the base blocks and drop them at the beacon's location. Replaced blocks are dropped on top of the beacon.

Bedrock won't be replaced.
