Waterskins
Waterskins do not "always" show up the correct amount of units left inside. i can force them to show up by dropping the container which hold a waterskin and pick it up again. i can also swap another item on it for that. same is durability for most items, best example tools while grinding.
-a solution, so far possible would be a additional symbol on the icon of the item. like a piechart. at least for units of water. so you dont need to move the cursor on it to see how much water you still carry with you.
-another point i already suggested recently and i'd like to see implemented is to make use of our shortkey, every game allows you to add potions to shortkeys, so water and food should be part of it in xsyon.
