Layer7 API Management

In API Portal v4.2/4.3 what are some common approaches that we can take to categorize the APIs as there does not seem to be any out of the box capabilities to group APIs.

1. Are most APIs marked Private by default and then added into a specific Organization if it has to be exposed to a limited set of audience ?
2. To categorize the APIs, say by domain/business function etc, would we need to implement a custom CMS ?

Correct, with API Portal 4.2/4.3 there is no option to categorize or group APIs.

But we have an outstanding feature request to implement this. I would highly advise to vote and comment on
