I currently have to create flow diagrams outside of Aha and paste in a static version that others can not change. This is very restrictive and does not follow the collaborative flow I like to use.
Thank you for your idea. In the time since this idea was submitted we have added Aha! mockups -- which make it easy to create flow diagrams directly in Aha!
Given the availability of Aha! mockups and historical support for this idea, we are unlikely to implement a Gliffy integration at this time. We hope you can understand.
