Example: self explanatory, however not only the selling to npc are limited to the hotbar, but buying items too. also it is not only limiting trade to be on the hotbar, but it is also exclusive to the hotbar Example scenario: 1)trade with npc while wirelessly connected to the ship that has to be filled, or emptied of its cargo Suggestion options: do not make the player wirelessly connect to its ship manually when is trying to trade, just let the player approach npc, press trade, and on the trading interface let the player choose among the invenotries that it can wirelessly reach via the scrollable drop down listbox that you have got already if a wireless connection is up already, then as the player is opening the trading interface choose that connection by default, and then let the player select the reachable inventories, and use the selected inventory to trade from, and to there (not necessary the one that is connected already) - or make the inventory the player selects to be wirelessly connected in the moment the player is selecting it with the dropdown on the trading interface
