Displayed items can be grouped by date, context, keyword, or project and can be filtered in various ways. A display of busy and free times is also supported, as is a ledger view of time spent that is suitable for client billing. Alarms are supported for events and repetition for both events and tasks in a powerful and flexible manner.
