Per Item Actions
Allow selecting a different action for practically any item on the ORF lists.

Bayesian (or Other Statistical) Filtering
Add a new statistical filter test to ORF. The most widely known and used statistical technique is Bayesian filtering, a "learning" email classification method. When properly trained and maintained, statistical filters work very effectively.
However, they require a reliable feed of actual legitimate and spam messages for initial training, so end-users are likely required to participate in the training.
