Placing of large objects is incredible frustrating. Even with snapping on they dance all over the room. It seems to help if you try to grab them by the center, but that isn't always possible. Ex: trying to line up a wall with a corner when the center of the wall is too far away or obscured by another object.
I would love if I could move a large object precisely no matter where I grab it from. If you can't give me that at least implement a fine adjustment screen in the maker pen where I can select a shape and then press arrow buttons to move it in single increments based on the current snap. Six arrows, two for each axis.
