As I create new releases, I need to be able to see whether or not I have "Sent to Jira." Given that sending a release to Jira is the key action that initiates the continued sync between Jira and Aha!, this is extremely important to visually see (especially in places such as the Features --> Workflow).
This feature has been shipped. When opening the Releases drawer, you can see in the integrations section whether it has been sent to JIRA. If so, you will see a link to the JIRA Version.
