Automatic roll-over of incomplete tasks
Some task managers (e.g. Good Todo) allow for the automatic roll-over of incomplete tasks to the following day. This saves having to re-date items that didn't get completed on time. Perhaps some users might prefer having overdue items listed separately by date (I find it distracting), which is why I'm suggesting that it be offered as an option under settings, allowing each user to select how overdue items are dealt with and displayed based on personal preference (could be a general setting or an option for each particular task entered).
