Question about deferring a task... and removing completed tasks in google.

I have turned off the feature that automatically moves tasks from yesterday to today. (Good.) EXCEPT, now if I manually move a task from yesterday day today, it no longer increments the # of times a task has been deferred. I love the little deferral count. Is there any way to combine those two features?

Also, if I "remove completed tasks" from Google tasks, will that delete them from WeekPlan? (That would be bad.)
