One tactic for doing this is to devote the Flag to marking the items you want to do today. Then you just use the "Due or Soon" action selector in the Context view to show those actions. You'll get all actions which either have a due date in the past, in whatever upcoming period you've designated as "Due Soon" (see the Preferences), or are flagged. You can narrow it down to only the flagged items by using the Flagged items only selector, then turn it off to work the due items, then go to Available items if you've still got time and energy left in the day.
