My suggestion is to add a right-click 'Sneak Peek' option to items that have a random chance at a reward. This option will display the possible rewards from the item similar to an NPC drop table, maybe with or without loot rates. Since I'm not familiar with all the items that have a chance at a random reward, I do know there are the Super Mystery boxes and Mystery boxes. I apologize is this has been suggested before.
I went through the pinned suggestions list made by 2 swords and the Handled suggestions list and didn't see this on there. Of course, I may have overlooked.
