If the tracker was already running, then it might be a good idea to provide an option to go back to the original item as a general catchall. Stopping tracking assumes that the person is not working. Not everyone is that detail oriented.
An example: As a contractor(hourly) I start hamster in the morning and try to document the activities I'm working on through out the day. I use gtg to track issues through the day, but when I'm not working on a hot item, I'm back in a default development category.
