When creating filters it would be useful to be able to filter existing emails for things like create date or last response date.I would foresee creating filters or automations that allow me to email a client that has had a reply sent to them but hasn't responded in a user-definable interval. If the reminder email wasn't responded to (last customer response > x days, but last agent/automated response was more recent) we could also possibly automate closing the ticket as abandoned.I'd be willing to dive into it myself if I knew where to start looking for defining filter criteria. I may just dive in anyway, but would be nice to have a headstart.Scott
