Linking activities to activity types lets you filter your calendar and detailed work report accordingly. As a result, you get a much better overview of what type of activities team members are spending the most time on.
Under Settings > My settings > My calendar and tasks > My activity types, each team member can determine which activity types they use most frequently. Simply tick the ones that you always wish to see displayed first in the activity type dropdown menu.Now whenever you add a new task or an event, the ticked activity types are at the top of the list for quick and easy access.
