Please add a configuration for the number of hours old a snapshot must be before it falls under the "one-snapshot-per-day" rule, and set the default to 24.
Why: I got a "new violations email" that had been sent at ~1:30 p.m. But by the time I received it and clicked through - around 3 p.m., the analysis had been re-run, so there were 0 new violations - despite the email in my inbox saying there were 3.
And because the snapshot with the "new" violations had been purged by the time I got there, I couldn't find any trace of those three in the history. So it looked like Sonar was sending random, wrong emails.
