Feedback Required: New Audit Trail Feature

I like the new audit trail feature Paul. But one obvious addition would be to add a mechanism to clear the audit trail, either wholly or in part by context. For example enabling the firewall context adds to the audit trail considerably, crowding out the other contexts as I suspect for most sites visits will be the most numerous events. So being able to clear that context from the audit trail from time to time, or to limit to displaying the most recent x entries, would be useful.
