Add the possibility to reorder subtasks by drag and drop even when the main list has sort order by priority. I personaly order main-tasks in a list and order them by priority when the due date is reached. But the subtasks of these tasks i like to order by drag and drop because they have all the same priority and i want them to represent the processing order. Currently i add a number preset for every task, for example: "1. open the door", "2. go through the door", "3. close the door" to order them correctly. If i use order by priority, the will order "close the door", ""go through the door", "open the door".
