When you sort by one of the column headers in list view, it will "flatten" the list so that the tasks get sorted together, regardless of what project or list they fall under. This is nice for seeing how different tasks compare with due dates or priority. However, there doesn't appear to be a way to do this for status.
For example, if I have List A, and under it are three tasks in different statuses, and List B with three tasks in different statuses, I want to be able to view the list view in a way that the tasks are _not_ broken out by list. I'd like the Open statuses for example in List A to sort right long with the Open from List B, etc.
