It would be very useful to be able to include addressbook lists in the filter rules. This enhancement would avoid having to create long filter rules where each member of a list has to be included individually in a "contains" rule. For example, one would be able to select a rule like this: "the <To or CC> <contains someone from the list> friends_list". The list would be evaluated at filter time, not at design time (i.e. the _name_ of the list would be stored in the rule and the rule would be evaluated in the moment the filter is applied). This way, if a list changes its members, the filter will continue to work as expected without changes.
