Hey there, love this mod. It allows for much more rigging than normal, which is saying something when it comes to Moving Box. (If you find a Restock Machine, you can put that machine in the box and take it with you into a secret room, and it's awesome)
However, there are two minor glitches I've noticed:
1: The box does indeed charge twice as much with The Battery, but using it consumes both charges.
2: Exiting a room without 'closing' the box (pressing space again) will delete everything inside the box.
I honestly don't know if anything can be done about these, but I thought I'd comment to maybe bring it to your attention

Great idea, watchmeojo, but what button would I need to hold down? Item activation one (Space), or drop pill one (Ctrl), or something else?

wym moving box is busted

this is a downgrade since it removes the ability to get items over pits, maybe if you hold down the button while its holding it above your head it works as normal?

Based mod.
