1. Unable to split items inside the Traveler's chest/Chest (example - I had 14 backpacks supplies and was unable to use them to rest, but due to weight I could not put them on the character).
2. Allow food to be used from the traveler's chest to be used for rest
Definitely! Both things I thought/found during my just-completed patch 6 playthrough.
I did really enjoy Wild Mage, though, and found some of the effects really fun. The one that swaps you with an enemy you attack sticks in the mind, both because I managed to cunningly use it to turn the tide on one occasion and on another forgot about it and unexpectedly ended up on the other side of the battlefield.
