App-TimeTracker-Trello
App::TimeTracker Trello plugin
http://trello.com
Using the Trello plugin, tracker can fetch the name of a Card and use
it as the task's description; generate a nicely named git branch
(if you're also using the Git plugin); add the user as a member to
the Card; move the card to various lists; and use some hackish
extension to the Card name to store the time-worked in the Card.
