Real-time tracking may be started automatically (see "Options"), by clicking the green button under the Time Sheet list ("Start current task") or by double clicking a task in the task tree (sets that task as the current task and starts time tracking). Clicking the black button ("Stop current task") stops time tracking. Time tracking may also be stopped automatically by using the computed idle time (see "Options").

While task working time is tracking current period start (shown next to "Active" indicator) and length (time indicator on the right side of the same panel). Currently active task full name is shown right under "Active/inactive" indicator.
