Feature - You can now use 'any' in the combinations section for the bottom block. This allows for single block elevators as they function on top of any block (air included). E.g: combinations: - 'quartz_block, any'
The above example will allow you to put any block under a quartz block and let it function as an elevator.
If you use the create command with an 'any' combination, air is placed as the bottom block.
