I think a great feature to add would be the ability to put a comic in multiple boxes (if this is somehow already do able I haven't figured it out). I collect a variety of comics for different reasons and I've run into issues with having boxes based on valuation and also based on storyline or a specific character's appearances. This forces me to choose where to store a specific issue rather than being able to share it to multiple different boxes. It's not a "game breaking" problem by any means, but it would be a nice feature to have available when organizing my comics.
