What to use due dates in OmniFocus for

OmniFocus, like pretty much every other task manager out there, tries to lure you into setting due dates for actions. Then it provides you with nice features to remind you on doing stuff: badges, special views, alerts - the iPad version even has a calendar-like screen for managing due dates.
The problem is only that - at least in my world - only a few actions have real due dates. Paying a bill, for example or filing the tax return. Everything else is more or less due asap, with different shades of urgency.
There is a certain temptation to assign artificial due dates. For example, I'm planning to post-process a photo project on the weekend, so I set the due date to Sunday. Then OmniFocus will remind me in time. However since it does not give you the slightest help in realistically planning the workload (like any other task manager I know), lots of overdue actions are inevitable. I have two choices then: ignore overdue actions, which renders the tools mentioned above useless or I constantly shift the due dates, which leaves me with the frustrating feeling of running constantly behind schedule.
That is why I'm only setting hard due dates, means that there are some sort of consequences if I miss them.
But how can I define a daily todo list? I can't.
So this is on the top of my wish list for 2.0: a way to select tasks for a day, a week or a month and ideally sort the freely, independent of projects and contexts.
