stephanhodges - oh I agree something needs to change, I just don't think that having more possibilities for which category a new card might be added to is the best approach - this is why I like my recently-added list idea, that way you always know that cards you've just created will end up there. Having a regular default category and a second, only-applies-in-this-session default category seems like a step in the wrong direction.
gato - that's already possible, actually; bring up the cards you want in a Manage Flashcards search, then tap on the More button , select the category you want from the list next to the Add/Remove cat buttons, and tap on Add to add all of those cards to that category.
