So, how category system works?

Key concepts

• Criterion: Rule applied to items.
• Category: Set of criteria used by a logical expression to determine which items will be collected.
• Section: Visual representation of a category in the bags or bank's windows.

Behavior

• Categories works as a lineal platform. This means in short: There's a list of categories, no tree, no subcategories.
• Categories works as a priority list. The first category collecting an item, will show it.
• Based in the above concept: There will be no duplicated items.

Criteria

Following is the list of criteria implemented by famBags, for 'Performance' column less stars means lighter.

Criterion	Description	Performance
Other	Accepts all items. This should be in your last category to avoid missing items. It will collect all items other categories didn't.
Type/Subtype	Checks for the type and subtype assigned by the game to this item. famBags doesn't modify or manipulates in any way the values of this parameters, just read them. Example: Type: Armor, Subtypes: Plate, Mail, Leather...
Quality	Checks for item's quality. Example: Epic, Rare, Uncommon...
Equipment slot	Checks for item's slot type in inventory. Only applied to items that can be equipped. Example: Head, Neck, Shoulder...
Quest	Checks if item is marked as 'Quest Item'.
Key	Checks if item is contained in the Keyring.
Empty	Checks if item is an empty slot.
Usable	Checks if item can be used.
New	Checks if item is marked as 'New' by famBags.
Incremented	Checks if item is marked as 'Incremented' by famBags.
Stats	Checks if item's offers the selected stats. Only applied to items that can be equipped. Example: Stamina, Strenght, Spirit...
Bound status	Checks if item's bound status. Example: Soulbound, Binds when equipped, Account bound...
Item level	Checks if item's level meets a condition. Conditions for this criterion are: Equal, Greater or equal, Less or equal, Between. You need to specify always a number except for Between operator which requires two numbers separated by comma (,).
Required level	Checks if item's required level meets a condition. Works the same as 'Item level' criterion.
Equipment set	Checks if item's belongs to any game's built-in equipment set. Only applied to items that can be equipped.
Outfitter set	Checks if item's belongs to any Outfitter add-on's equipment set. Only applied to items that can be equipped.
Name	Checks if item's name meets a condition. Conditions for this criterion are: Exact Match, Contains, Starts with, Ends with. Comparison is always case sensitive. Example: ['Essence' - Exact match] will probably not match any items, while ['Essence' - Contains] will match all items containing the word 'Essence' in their name.
Spell	Usable items exhibits a property called 'Spell name' representing the action they will trigger, i.e.: Normal food's spell name is 'Food' while normal drink is 'Drink' . This criterion will check if Spell name meets a condition. Works the same as 'Name' criterion.
Categories	Checks if item can be collected by specified categories. This criterion if not used wisely can heavily penalize performance so you must use it as last resource.
