Scrip to leverage RT-Extension-HistoryFilter?


I want to improve the signal to noise ratio from our system and due to
early decisions on the need for notifications, we send too many info
messages. Does anyone have a scrip that leverages the HistoryFilter
user preference setting to control the types of transactions for
which Email is sent, not just in the ticket display. Before I write
it myself, I wanted to see if there was existing code that could be
leveraged. Any pointers will be appreciated.
