While I'm happy to sometimes keep my trill board sync with Aha status, I sometimes don't want. We use a board to manage the content of our demos (we create one column for each new demo). It's nice to be able to export a feature from aha to Trello, but I don't need status sync in that case. Plus, when I did setup my configuration, all my columns didn't exist actually as I'm adding them along the way.
One of the key goals for the Aha!/Trello integration is to allow product teams to push features and requirements from Aha! to Trello and to get list/status changes back, so that the respective teams can stay in the tools which were made specifically for them.
While we can understand the use case, at this time, we do not have plans to make changes in this area based on community feedback and current priorities. We hope you can understand.
