Just like on the great RTM iPhone App, I would like to see a weekly ordered view, where the tasks are sorted by day.

Right now it's only possible to see the tasks sorted by day for today and tomorrow (in 'Overview').

E.g. if I want to check today (Thursday) what my Sunday's tasks are, I have to have to check every list and look which of my tasks are due on Sunday (or instead look on my iPhone).
