I'm not sure how PocketStackZ! got released without any new features at all so really this should be a bug.
There should be some form of RepeatAdvisor functionality on the PPC version.
At a minimum it would be great to select all of the Untest cards and all of the Expired cards from the current selection.
(Maybe add an extra dividor in the same menu where you choose "Repeat Advisor". Under "Untest on Top" you could have two more check boxes.)
