This mod allows a lot of new decoration things and looks very cool. It is easy to use, however, the selectionbox is annoyingly big in 5.6.1. (I know this mod is built for the upcoming version, tho.)
A small thing that annoys me is the giant smoke puff in Minetest Game when a lead "dies". Another small thing is the chat message. I would remove it because it quickly fills the entire chat if you misclick.
The only thing I’m missing is some subtle sound effect for attaching/detaching/etc.
