First suggestion, remove the collections quest or refine it.
Anyways beyond that: Can you allow us to queue up multiple things in the collection menu - the field refill buff might be real nice but sitting there clicking every 5 min is a major pain. Rather just queue up 25 of them and use them later.
2nd thing, during multiplayer adventures, can you give us the option to 'mark' a spot on the map with a flag to show the others playing the adventure where you mean(As in 'move your general here' or 'attack this')
