Timestamp for task completion

Explain the problem as you see it

I would love to easily pull a list of tasks I completed yesterday or last week. It would be awesome to have a "date completed" field in the Task supertag so I can do easy look-backs.

Why is this a problem for you?

I want to know what I got done in the last day, week or month.

Suggest a solution

This could be done with a search node with a date filter on when the task was completed.

I can add a custom optional field for "Date Completed." However, I have to manually add the date. It would be great to make the Date completed set automatically, but I'd have to write some code for this.
