Advanced Search + Save in ZMail

Is advanced search in the roadmap for ZMail? I really like new features coming out in stand alone programs (no one has the integration potential you guys have). Yahoo! Zimbra desktop allows you to create these extremely intricite searches that work like dynamic "Folders" and then save the search.

Actually, you know what would make a lot of sense? What if Zoho bough Zenbe? Then you'd have full featured mail already done! You could focus more energy into other programs.
