Common use cases would require you to rewrite the same App Action over and over. With App Action Categories you can simply reference one of the pre made schemas, without having to redefine the same interface multiple times.

Let's assume your app needs to perform an operation and needs to trigger a notification to different services. Utilising categories, you can simply call App Actions whose category is `Notification` and ultimately integrate with all of them at once: you will only rely on the `Notification` and you are good to go.

Additionally, App Actions with some specific App Action Categories will show up in
specific locations of the user interface.

App Action Categories are versioned in a semantic way: the first digit indicates a
breaking change and the second digit all the other changes.

## List of App Action categories
