Thanks for your feedback! It sounds like you'll like what we've already done in OmniFocus:

#1: You can assign a due date as a reminder to yourself (and you can assign a start date if you want to keep something off your radar for a while), but we expect that most tasks won't have them. Your next task for your project is whichever task is next on your list.

#2: There are no dialogs in OmniFocus, you simply enter your tasks in an outline (just as you might in OmniOutliner).

#3: The priority of a task is simply its order in the project, and you can drag and drop (or use keyboard commands) to change the order around (just as you might in OmniOutliner).

#4: The tasks in a project are hierarchical and collapsible (again, just like OmniOutliner—are you sensing a theme?).

The one item that we haven't yet implemented is #5 (since that's not just like OmniOutliner!), but we've talked about presenting exactly the view you describe—we're just still in the process of debating exactly where to*put it and how it should be implemented.

Thanks again for your feedback; we're very much looking forward to sharing our first beta with you all!
