When you go to a project, tasks are grouped by list by default. But if you sort, those groupings are abandoned and the tasks from all of the lists are mixed together.
I'd like to be able to keep tasks grouped by list, but still sort by another field, such as created date, within each grouping.
It seems to me that the easiest way to do this would be to allow the user to choose a value to group by in addition to a value(s) to sort by.
If this isn't clear, please let me know.
