Inventory user interface

Information displayed and interactions possible in the inventory (sub-)screen.

Information

 * Item grid 50x50 or 64x64 pix, which displays item icons (one icon represents all “.45 bullets” in the inventory)
 * Sorting (weight, bulk, nutritious value, quantity <- what else? type?) and filtering (equipment, food, weapon, consumables, other <- what?) status display
 * Icon area contains small text showing quantity/bulk/weight of item
 * Items not usable/equip-able (lack of skills, broken) are marked (desaturated? <- needs to be put into requirements for GUI, marked with red “/” sign <- will make inventory look distracting)
 * Quick look (under item grid?): one-line summary with item name, condition and influence?
 * Total inventory bulk/weight (color bars or numbers under item grid?)
 * Item description (separate page?)
 * Name
 * Quantity/weight/bulk
 * Status/condition
 * Statistics (what statistics?)
 * Influence on character statistics/abilities
 * Description
 * Equipment paper doll (separate page?)
 * Worn items <- would we use slots for that?
 * Equipment-specific stats (armor value, damage, protection against cold) for easy overview
