Hi,
it could be very helpful, if Tasks can be sorted manual even if there is a sorting rule selected. And, with a tap, the list will be sorted according to the rule again.

- redundancy spoiler-
Due to my worse English, here an example:
I have set a list sorted by "priority/due date/modified date"
But I can move around Tasks by drag and drop anyway.
With a tap somewhere, or better a gesture, the above mentioned sorting will be applied again.
