Thanks for all your hard work on this release! Please consider adding some simple new objects in the next release - specifically for my courses I could use a “small part,” something about the quarter of the size of a lid, as well as a large “WIP” bin to catch them as they come off the conveyor 🙂 Thanks as always either way, Shawn ---
