Initially when I coded the feature I did not think that people would want to set the expansion for cards that were only ever printed in one.... but it seems some people do.
I'll think on it.
Some of us want to use this site to inventory our cards, and be able to have each version of the card listed separately by expansion. I know... strange, but there is no accounting for taste. :-)
I'd love to be able to enter my cards in by expansion, and be able to list them that way.
Quick example:
Lets say I only have 10 Fireball cards. 3 Fifth Edition, 2 Darksteel, and 5 Archenemy. (For sake of the example, that's my whole inventory...)
If I filter my inventory for Fifth Edition cards, I should only see 3 Fireball cards. Instead I see one line showing 10 cards, and the edition shows as 2011, not Fifth like I tried to filter by.
This would be very cool if I could actually see the actual cards I own in the list.
Does this help with a direction to think? (I know what it's like to have someone ask for your program to do something you never imagined it would be used for... fun stuff.) :-) Keep up the good work!
