This game throws a large variety of lootable containers at you over the course of exploration and inventory management becomes a sort of mini-game in and of itself as a result.
A very useful feature would be to allow us to mark items as "Auto Extract" such that any time we loot that item in the future it would be extracted to essence. This would help to seriously cut down on how often a person has to open and discard things from inventory, keeping the pacing of the game more interesting for the players.
