Some shelves are almost self-descriptive but others are more based on feelings. To make it easier to share those feelings to whoever sees that shelf, an optional description box would be a fantastic tool to give reasons on why did you add that particular game to that particular shelf, something that might or might not match with your review. I’m not sure, first, if that’s something everyone would like to have and, second, if that’s easy to program.
It would be cool if grouvee had a listing feature that you could share. Or if you could share your custom shelves!
