Categorizing the tickets can give you a lot of valuble insight in what your users are struggeling with, when certain types of requests or incidents are on the rise you can target this with a sollution or other measures. There is no built in method for caterories other than SR or INC. You can use custom fields, but that brings us to the next point, reporting
Even if you use custom fields for categories, none of the reports give a good overview of ticket categories and ticket trends. All reporting seems to be revolving around agent efficiency. I would like to see more reports givving me statistics in these areas. The fastest way to accomplich this, would be to allow downloading the raw data so we could make our own reports using Excell or similar, but built in templates would be nice.
