I got some ideas for items:
1. Laptop - A portable computer for viewing cameras, photos and buying some sort of items.
2. Beacon for drone - A special beacon to which the drone flies. Add button in the store UI that enables delivery to the beacon.
3. Hand cranked flashlight - A flashlight that is rectangular in shape and has a handle on its side. When you hold rmb (right mouse buttom) holding this flashlight, the handle will spin and the flashlight will charge.
