If you’ve read my post on why Managed Masters are bad and referenced Masters are good and you are taking the time to convert your library over to Referenced, you might like to determine which files are still Managed.

Luckily with Aperture 3 it’s easy to determine the status of a photo using the Smart Album.

Simply create a new Smart Album and select “Add Rule” and select the “File Status” rule.  From there you can select whether you want the Smart Album to include Managed or Referenced files.  Close the Rules and name your Smart Album something useful such as “Managed Files” and you can instantly see which files are still managed or Referenced.
