Add a preview to the elevator with a GUI, if not add it so the wrench when clicking on the elevator shows a ghost image of the blocks its going to use.

Maybe add (if going to add a GUI) an option to travel end to end on elevator use. That way redstone wouldn't be needed and in a chain of elevators, just using the machine as a button would trigger it to travel the other direction till the end.

Also there is a spelling mistake when it does not have enough power. It says it doesn't have enough power for the paltform.

Also as balance suggestion, even though its cheap... i felt like crafting 12 elevators for a section was a bit much... maybe have it so 1 recipe does 4 or 8? I would be a fan of 4 personally.
