OK- so you can edit a named view using a “Named view widget”. In the Named Views panel, select a view and check the “Show named view widget” checkbox - you will get a camera you can edit, and you will be directly editing the named view.
So in other words - we have cameras. You just have to turn them on.
There is also a way to edit a named view by looking. It looks to me like you haven’t tried any of these tools.
As I understand your request, it is essentially - I would like named views to be exported as cameras in some specific file formats. Is that correct? If so, that should be an easy thing to implement. Just tell me which file format you want us to do it for.
