Just a 1.13 update. 1.13 changed the JSON behind the code a lot, but it wasn't really a big change for this...Though, I have been considering adding to it.
If this breaks in the future from another 1.13 release, I'll be sure to update it. You may need to let the config regen itself for this to work.
Let me know if you think that creating custom recipes for elevators with custom max block lengths would be neat. Maybe support other coloured blocks instead of just wool.
I may look into this for future versions. (Busy right now updating other much harder plugins to switch)
Enjoy
