Is it possible to make a plugin to prevent dropped items from disappearing after they have been left for some time, and prevent these items from being picked up by others? This way it is possible to have an actual shop with items being laid out in display cases. Perhaps, if one is an OP, they will be able to type something like "/itemdrop" to turn the plugin on, and any items they drop will have these properties (not being able to be picked up and prevention from disappearing) and then type "/itemdrop" to turn this off again. Sort of like how the lampstone plugin used to work. What do you guys think?
