Task : Due Date & Date Completed ? Audit Trail ?

Hello,

I am testing Zimbra 5. Currently I work on task features and I have 3 questions :

1) Is it possible to have a "Date completed" in addition to the Due Date.

2) If the task description is changed, to have an audit travail (who has changed it, when, ...)

3) Having a different color and a searching tools to see items overpast due

4) Having a new column with the owner of the task (in case of deleguated task)

Thanks
Christopher
