Setting appropriate icons for metamodels

Next Design allows you to set icons for each metamodel.
Setting appropriate icons for each metamodel makes it easier to identify model classes displayed in the model navigator, etc.
When you add a metamodel, a default icon is set, so you need to set an appropriate icon.

For example, you can set a folder icon for classes such as packages and groups that have the responsibility of consolidating multiple models, and
For classes that are input/output interfaces, you can set a port icon to make the class's responsibilities intuitively clear.

Below are examples of use cases and actors with default icons and with appropriate icons set.
