When playing poker, RPGs and board games, you often have piles of objects that all players need to use. (money, dice, chips, etc.)
I propose a tick box that sets a container of something to infinite - basically the number of items in that pile is frozen, so you can infinitely draw/deposit items in the stack.
The items that this property could be applied to are: decks, stacks of chips, bags - any container really.
Now obviously these containers might contain more than one type of object, so with 'infinite' on, these items should return the item that is on top of the pile regardless of whatever else is in the container.
This would mean that you could have bags of infinite dice, an infinite poker chip bank, or endless 'decks' of monopoly notes. Obviously it would be advisable for GMs to limit this role to officers, so people can't make their own piles of money infinite.
I have some experience with Unity, and if the containers work like I think they do, then hopefully this wouldn't be too hard to implement.
