Hi Brian, yes that's correct, the styles list is saved to a .3dm file and will be restored when loading the .3dm file back again. If a template file is set, the styles in it will be used for the initial styles list when MoI starts up and when you do a File > New.

If you build up a set of styles that you want to save for later use, you should save to a .3dm file which will then contain them. That's the same as if you build up set of objects that you want to work on more later on. When you create an object it does not stay around permanently, they are saved to and loaded from files.
