I'm nearly BEGGING for you to do this and I know it must be easy because it's actually already partially done.
Have the web portal show the task title in bold whenever the status is ACTIVE. As we know, the status itself becomes bold when the task is active so then just extend this same formatting to the task title. It would basically look the same as if setting the due date to today or earlier. I know one might say "Well Tony - just set the Due date to today or earlier" but the thing is this - we should still be able to get this awesome bold formatting and still use the due date as what we need it for - in essence to document the actual due date and not as a switch for bold titles.
I cannot tell you how much this helps in being able to print your todo list and track each task individually.
PLEASE PLEASE PLEASE make this happen - I know others will thank you along with me...
