Taufik, thank you for the question! We know that the UI for icon families can be made better. 😢 At the moment, it is not possible to delete a family, but there are some tricks you can do that can make your life easier:
- If you remove all icon sets from the family, it will become invisible to the customers. It will not be shown on your icon shop page.
- It is a good idea to rename the families that are duplicates or unusable, so that you don't get confused when adding new sets to them. You can do that from the Manage icons page.
I am sorry that I cannot give a better answer at the moment. Hopefully, we can have better functionalities for icon families in the future.
