We have a lot of categories because we share our ticketing system with another type of technology support and because of how close we work with the other department most of us have access to all categories. This leads to having a large list to scroll through during ticket assignment. Its not a huge issue but it would be a nice quality of life change to allow techs to re-order the list as they see it.

I could see this being a setting that has to be enabled either per user or at the top level to allow. An simple example might be allowing techs to create a category 'view' or 'profile' in their account settings and changing that to the default view for themselves or something like that.
