It would helpful to be able to assign a highlight color to certain models in the model dialog. A lot of the time the files I'm working in have many different models and it can be difficult to locate the one I want quickly. I can give them appropriate names to differentiate them, but based on certain naming conventions, I end up with several similar titles that make them hard to distinguish at a glance. If it were possible to color code the models in the dialog I think it would be useful tool for users to keep their models more organized.
