ok thanks. To clarify:
What we want to add is an explanation to the multiratings of WPGeoDirectory. If you have a rating “Cleanliness” or “Pricing” everybody knows what it means, but as we are creating a specialist site, we need to have some room to include an explanation. Just one or more sentences that appear in the frontend and give guidance to the review process. This description could be displayed under the title of the ratings, or as a popup when hoovering over a question mark icon. At the moment the add-on allows to specify a title and image, but not a description.
The multi-page thing is just nice to have. As the fill-out form would become big, multiple pages would not be overwhelming for the reviewer. But as I said, it’s nice to have. As an example, AirBnB uses this to break down the review proces.
