It is a little disappointing that the introduction of the new priority field did not also factor in the due date when sorting by priority order! I prioritise all my tasks and used to use labels to do this (which I now may have to return to).

I have a number of tasks at each priority so when viewing them in summary view they should I suggest show then sort into due date order beneath that to make it usable.

Disappointing that this was not considered when being developed.
