Often times a task will be added that does not need a date. If a data is accidentally selected, can you clear it so it does not have a due or start date? I would not want it to show up on reports or dashboards. eg. A task titled "Weekly Meeting Notes" - I like to have it as a task so it is easily accessible and organized for the developers, but it does not need to have a date, as notes "comments" get added weekly about what was discussed during the meeting.
