The main KArm window has the following components: menubar, toolbar, task/time window and status bar.
The various tasks are displayed in this window, along with the time accumulated for each in the current session and in total. Tasks being timed have a small clock icon next to the session time.
Subtasks can be created for each task. Double-clicking on a task displays or collapses its associated subtasks. The total time accrued for a task includes the times for its subtasks, as well as its own accumulated time.
