Task Followups

Hello, For me, out of necessity to follow-up with people on emails and tasks, I have created a category in Outlook for each person.  Then, in outlook use Control Shift G to set a follow-up date/time.  I can look at my tasks by Category(person) and follow-up with them.  I currently have over 1,000 tasks.  I sure hope the new Planner and Tasks can make this process simpler.  Comments?
