Good start

Good start, but this could be a million percent more useful if you simply added the ability to edit the query instead of just appending something.

For example: a query like this will never work: /wp/v2/pages/(?P<id>[\d]+)

I agree it’s nice to have it as a reference, and it should defenitly stay, BUT when you click on it, you should have an options to edit the query to turn it into /wp/v2/pages/123.

I know I could get kind of the same result (except it will be wrapped inside an array) with /wp/v2/pages/?include=123, but meh.. Anyway, I’ll probably modify the plugin and create this myself, as it seems development has ceased.
