Not sure if it would be useful to anybody or not, but just from a database perspective, I think it'd be cool to have more scan upload options on the site.
I think instruction manual scans would probably be the most useful to people, but I also think having scans of the top, bottom and sides of boxes could be cool as well.
As manuals are not any set number of pages, I'm also wondering how the upload process for that would work.
I can understand not wanting to make the submission page too long from a design perspective, just for ease of use, but perhaps these additional scan options could be hidden or shown with some "advanced scan option" link?
