New feature to Sort, Search and Clean old emails
New version is good. I like the search by documents. One feature i think if yahoo can add would be great is we need some kind of new drilldown page (may be named as "Sort,Search and clean"), which shows some kind of count vs email address. Eg: firstname.lastname@example.org ---- 500emails.
This ways, we can cleanup the emails and reduce the load on Yahoo too.
