It would be great if cards created in Trello were automatically added to Aha! If you have a list for new features in Trello, adding a card to that created a feature in Aha without the need to re-upload the entire board.
We just released an enhanced Aha! integration with Trello that allows you to have full control over the way information flows between Aha! and Trello — in both directions. Cards created in Trello will now automatically queue for import.
