This question addresses a feature I plan for my cyberpunk extension The Dark Module. It will eventually have an unified inventory, on which every item will be part of the same tool belt. I would like to know how I can combine weapons with item definitions, making them appear and be possible to select from the item browser. Basically I want to make the Blackjack / Sword / Arrows appear in the same inventory list as the Lamp / Compass / Lockpicks / Readables / etc: Just as you select the Lamp item and hit the "use" key to toggle the light, you could select the Sword item and hit the "use" key
