We would love to evaluate the Time a ticket was opened (not just the date) and see if it falls between 5:00PM and 8:00AM in the action rules. This alone would allow us to move away from Alert Central. We would then leverage that info and Ticket priority to notify our alert our on-call technicians. This seams like a fairly easy update/add and would be HUGE for us.
Something long the lines of:
[Time] [opened] [between] [{time}] and [{time}]
or
[Time] [opened] [prior to] [{time}]
[Time] [opened] [after] [{time}]
