I would like the ability to trigger notifications based on the result of a Harbormaster buildable. I would imagine the end result would allow you to set a build plan and status/statuses that you would like to filter by. I see this as being important for long running tests that should alert someone as soon as a failure is detected as I can't depend on all responsible parties to check the harbormaster application hourly.
I'm willing to do the work for this feature.
