When adding/editing an Action, you can easily create a new category.

1. Open the Add Action window (Cosmos > MENU > Add Action).
2. Enter your information and click on the category drop down list.
3. Go to the bottom of the list and choose “- New Category -“.
4. This should bring up a window for you to enter a new category name.
   You can also specify if you want it to live under an existing category or not.
5. When done, click the “Add” button and save your Action.
   (Note that the category won’t actually be created before you are saving your Action into it).
