In task view, give us an option to show the number of days until the due date or a countdown until due; essentially the opposite of # days overdue (instead of the date).
With just the due date showing, I can't tell how many days until the due date unless I flip back to the calendar view and count them. I'd like to know how close it is to the due date for a given task. Thanks!

Add a setting that allows the user to determine if the subtasks show expanded or collapsed.

Sort tasks by two parameters - e.g. By priority then by project. This way tasks can be better visually separated. So eg high priory tasks would all be together but home verses work projects could be separated (and seen altogether because the projects would be coloured differently)

Ability to add tags to a project

Currently, when you select a project in the task view and you enter into the table showing the tasks for the project you selected, you'll find a sort box in the upper right of the form. The sort box has a number of fields from the task form listed in it. Please display these fields in a table (at-a-glance format), AND please make these fields dynamically sortable in the table view. Thanks! :)
