The current ticket system allows a Priority of High/Medium/Low with a default setting of High on new tickets.
It would be useful to be able to define additional Priorities/modify the current ones (maybe an extra 1 or 2) and also to be able to set the default setting either globally or by category.
For example:
Urgent (Site is down)
High (Response requested within 4 working hours)
Normal (Response requested within 1 day)
Low (Response requested within 2 days)
