If a user has marked in his/her calendar task delegations, upon return after the delegation period the tsk may still be incomplete and the original task assignee might want to complete the task himself/herself. However, since his/her calendar had the days marked for delegation he/she has no overview of the tasks.
Proposing, for calendar delegations, let the original assignee also have an overview of the tasks assigned that were delegated and give the original assignee ability to complete the incomplete tasks
