It would be good to be able to view the request history from a task screen itself, as a process goes along people might have added comments and notes etc so it would make it easier to be able to view these from within the task screen itself and not have to open the request and then view it's history.

It would also be good if we could also add filters to the field so it won't show system updates when tasks activate etc, so we could drill down and only show what is needed
