I would like to be able to record the resolution when a ticket is resolved, along with a resolution category. You could also add an checkbox that added the resolution to solutions. This way it would be really easy to add solutions, or at least draft out the solutions while the incident is "fresh". Then you could go back and make a solution article when you have time, or assign the writingto someone else if you have that kind of resources.
Resolution categorys really are helpfull to report on when trying to get an idea of what kind of issues you have, and what causes them.
