Pros

Omnifocus allows users to setup the "defer date" which can be treated as "start date". Tasks will not be marked as available until that date, which should help to focus on the "available" task only.
Pro Forecast summary
The forecast summary shows a quick digest of the tasks you have for the day. You can select any day to quickly see what tasks you have planned that day. For extra functionality you can connect with the iPhone’s Calender app, which allows you to also see any other events you have planned that day.
