When adding cards to you collection it would be nice if you could choose the default Set to use that will override all other set options. For example if I have something that is in the NEO (kamigawa neon dynasty) set that also exists in one of the core sets, it will automatically add to my collection as NEO when this option is enabled and NEO is selected.
This would be a really nice feature to have after buying a bunch of cards from a particular set and getting them quickly added to your collection.
I was hoping the filtering by sets would do something similar when adding cards but it does not.
Thanks for the great site!
