I'd like to see an option to include a sequentially incrementing number (basically an autoincrement DB column value for the ticket).
One of the drawbacks of the current scheme is that it's not easy to get a feel for how old a ticket is. You can include the date, but then another 6 random digits need to be added. This makes a reference that's way too long to take in at a glance.
Something like %6t, which would generate a ticket number with leading zeroes with a minimum of six digits (e.g. 001234) would be brilliant.
