Requesting a simple feature: Option to Lock and Unlock items. Items that are locked cannot be discarded, sold, converted to material, traded in for seals, traded to another player, or listed for sale. To lock, right click on an item and select Lock. To unlock, right click on an item, select Unlock, check a box on the confirmation window, and confirm the window.
Reason: Adding a lock feature would make it easier to avoid unintentional item loss, and thus reducing player complaints and GM workload.
For example, selecting the right item to turn in for seals can be tricky. When I was using green dungeon drop gear, I removed items that I intended to turn in for seals from my Armory Chest and filtered the selection window to only show items in Inventory, however I still felt uneasy every time I selected an item that looked similar to an item I wanted to keep.
