Link Tender support tickets to Pivotal Tracker stories
Chrome extension for linking Tender support tickets to Pivotal Tracker stories
With this extension installed, a white rabbit will appear whenever you visit a Tender support ticket in Chrome. Follow the white rabbit (by clicking his button in the address bar) to create a Pivotal Tracker bug that will be linked to the ticket.
Following the white rabbit gives no indication that anything happened. You'll have to visit your Tracker project and look for the new story in the Icebox.
