I realize that Modules is essentially the Grouping method, sort of. But it would be nice in the Site Settings a way to group the default work types. My company has so many different types of services that the list gets pretty long. It would be nice if there was a collapsible row that could have categories. Once the row is expanded we see the sub-categories. I don't necessarily need to see that play over into the projects, tasks, or timesheets since those get assigned when the project is created.
