"Custom Script" action for Ticket Filtering
Some useful feature which I've already suggested in "Call for plugin ideas!", is a 'Custom Script' action for ticket filtering.
It means that with a specific conditions for a ticket (e.g. from special email), set the action to run a Custom Php/etc. script rather than just assignment and static actions.
Also I'll appreciate if anybody let me know any ticketing system which already has this feature.
