Tried to give this a full test and it seems all the features are not yet functional:
1. One feature I would suggest is that you add the ability to use the 'Skeleton Key' to open the chests. If you use regular lockpicks and you fail at opening the chest, then you risk losing one or more random items in the chest at each failed attempt.
2. Telekenisis - select the trunk you want to Tele and it warns you if you are close enough to take damage or Tele's the trunk otherwise. I know my Treasure Hunter does not use the 'Remove Trap' Skill as Telekinesis is just easier.
3. What would be cool is if you could time an Invisibilty Spell to go off just as the chest is fully un-covered. (If you move now while the chest is being dug up the digging operation aborts, which can be a good thing if you see a team member is not ready or if your Pet has wandered off to kill some random spawn). Being invisible would help keep one alive, especially doing Levels 5 and 6 Maps. Of course, I try to do this manually, but sometimes the chest is blocked under a tree and I can see it coming up.
4. A Chest Looter that will get out all the good stuff (forged pardons, creeping vines, Essence, the Skeleton Key, another Treasure Map, Surge Shields, Alacrity Scrolls, SOT's, etc.) then analyze what is left and grab anything good -- perhaps a filter to not loot certain items at all such as reagents, rings, bracelets, wands, etc. -- a callable version of the Claw or Miffy's?
5. Send the gold in the chest via BOS to the Bank
