I think it's time somebody invested time into making a snip of code that supports item stacking. By item stacking I mean: say you have a pill. If you pick another one up, a small number would appear on or next to the icon in your inventory displaying how many you now have.
Kinda like this, or something similar.
In the code, players could specify the max amount of a stack a player could hold for that item/weapon.
Id recommend the hard limit being at 99 to save a third digit space.
I'm not sure if this is possible the way Id want it without a client
(which would be optimal to not resort to), but Id like to hear some feedback on this: what would work, what wouldn't, what is impossible to do.
