I am a new user and getting familiar with the system but I agree with John Beck in that it is frustrating that order of tasks change in the different views.
I produce my tasks in the Gantt view in the order they need to be done but when I go into the other views they are in a different order. Even if I select Date order in list view it is still different to the date order in the Gantt view.
It would be useful if they could be put in the same order but then allow the users to change the data shown in each view ie if we would want by due date or priority etc.
