this may be an extension of an old idea, but with the recent release of Program Member Custom Fields, it would be nice to add these as filters on reports. Specifically Email Activity reports (if not all others). Filtering the smart list by member data returns the lead, thus invalidating the report if attempting to only filter by Member Fields.
Example:
I'm tagging a custom program member field "Is Customer" to see if, when the email was sent, that person was a customer or not. I'd like to pull a report of email activity where "Is Customer" is TRUE (and vice versa). However without a filter, I have to do it in the Smart List filter which pulls all emails sent to that person as long as the person was TRUE at any point, not point in time.
Bonus:
All Group By to read these fields as well; much like Segmentation does today.
