It would be great to be able to quickly select items from My Agenda that I intend to work on each day, and see just those items in a filtered list.
It would be nice if this worked for both scheduled and unscheduled tasks. I have lots of non-urgent tasks that aren't scheduled and get done when time allows, and this would help with managing those alongside the scheduled tasks.
This is a feature of the Microsoft "To Do" app that is great for daily reviews and task prioritization, and allows for changes in priority that may occur in a given week. This fits into the "Getting Things Done" (GTD) productivity method.
Seeing the filtered list of tasks helps with maintaining focus and avoid being overwhelmed or distracted by the large list of all assigned tasks.
