I've had a go at adding the basic trackerbot functionality to: http://ex.seabright.co.nz/helpers/patchtrack
This page lists all revisions on a branch. Any revisions that don't have a corresponding ticket are marked in orange and have a 'Create one' link. Clicking this link takes you to a pre-filled out form that will then create the ticket.
It's a manual process at the moment as I wanted to sort out the formatting and content of the tickets before having the bot do it automatically.
Note that the database behind this only updates once an hour. If you make a change you unfortunately won't see the effect for some time.
Thoughts?
