Combine the power of Zendesk tickets and the simplicity of Github issues for support nirvana.
GitZen is your one-stop dashboard for viewing and managing associations between Zendesk tickets (user-facing and probably linked to specific customers who requested the change) and Github Issues (developer-facing and generally technical). Simply add a custom field in Zendesk with the Github ticket number plus a product_enhancement tag, and you can quickly see the status of all tickets and their associated Github issue. Fundamentally, GitZen is a communication tool between your support team, your development team and your customers.
See the GitHub page for usage and development instructions.
