Got 2 more suggestions:
- Mannequins with any armor/clothes on it. There's no way to see what you placed on the Mannequin. The only way to see if you have something at all is if part of the mannequin becomes invisible in Tedit. It could also use a tab like Chests so we could put or remove anything down. Currently, the only to add stuff on Mannequins is to go directly inside the game...
- Magic Dropper tool to make water drops. Unless this is already possible by adding a block of water inside a brick? Referring to this btw -->
