Email Address Lists and Category colors

Is there a way to get Clearwell to make a report of all the individual email addresses?  I know of the "Participants" tab in Analysis and Review, but that's not a list of the email addresses (necessarily) and it's not exportable.  I would love a listing of all email addresses.

Also, is there any way to search pst emails using the category colors?  We have emails that are marked different colors, that have meaning, and would like to sort/search but I don't see how.

Thanks!
