Searching for completed task list in Task Manager.

With regard to Task Manager, there is a requirement that completed tasks MUST NOT be vanished and shall be remained in task manager.

In current system, user only could find how many task awaiting for user action is and delayed or not.

However, as I mentioned above, completed task CANNOT be found in task manager.

Every Completed tasks for each user are extremely important for each user.

For example, each user could find easily how many tasks have been completed for a specified or periodical duration.

In addition, a User could find the history regardless of BP and project.

Without this function of task manager, user must find the record by shifting each Project and BP one by one.
