Feature Wish: Filtering by overdue tasks and marking overdue tasks

[fthommen]

It would be great, if

1. in the listing there could be a filter for overdue tasks (e.g. status=overdue)
2. In the listing (and on the page where the tasks are defined) overdue tasks could be marked (e.g. by a red background)

a luxury feature would be, if even tasks approaching their due date (by a configurable time) could be marked (e.g. by a yellow background).

Cheers
