Some of my add on requests =D
Rope: Could be used to tie people up and you could have a special knife that can cut the rope. Also you could be able to tie a vehicle to a lampost.
A Shop mod: You could click on a bot then a speach box could come up you type for instance Buy jeep then you will have a special spawn brick that you can place somewhere the your vehicle/item will pop up for only you to take then the spawn vanishes.
