Thank you for your post.
This post is more of a product suggestions, so I would encourage you to enter this information into our "Product Suggestion" web form at:
Yes, I could copy your post and paste it into the web form, but there are additional questions asked that only you can answer. Also, since these entries are monitored and read by members of Product Management and Development, more weight is given to customers rather than members of Testing or Technical Support.
Agree with your assessment. That would seem to confirm I'm not missing an existing means of clearing the Recent Files list.
