It would be very nice to click "Start Timer" on a JIRA issue and Tmetric would auto-detect an existing task with this issue ID.
Then tmetric could continue this task.
Now each time you click "Start Timer" a new task is made in Tmetric.
The main benefit to fix these would be that the Project and Tags for this task will be kept, and you don't need to adjust these manually afterwards.
Another time-saver and makes useability of tmetric much better imho .
