• Sum a property (good for weight system)
• Sort items using a property value (ascending alphabetical only)
• Flood system : add items automatically and when they reach the maximum of the slot, they go in the next empty slot

Systems

• 3 systems available (Basic, Named slots and Grid)

Basic

Use numbers as slot identifiers to retrieve your informations

Named slots
