Sorry, just noticed there was another post saying basically the same thing.  Just adding to the chorus of voices who want this feature, then!

I know this has already been requested.  But I really, really, really want an export feature that contains all information for all cards in my inventory.  For me, this one feature is more important than any other on this site.  I don't want to spend hours upon hours putting all my cards into the site, but then not be able to save that data elsewhere should I so choose.  Pretty please?

Otherwise, awesome site! I love it, thanks for this resource!
