I think it'd be nice to add a
title="" attribute within the shortcode ( http://www.davistribe.org/gde/usage/ ).
[gview file="http://www.ok.gov/OREC/documents/Contract%20Info%20Pamphlet%20(11-2012).pdf" title="Oklahoma Residential Sales Contract Information Pamphlet"]
This would allow the download link to say:
Download "Oklahoma Residential Sales Contract Information Pamphlet" (PDF, 469KB)
Download (PDF, 469KB)
It might also help for SEO.
P.S. Your "NEW! See what's coming in GDE 2.5" link ( http://www.davistribe.org/gde/beta-program/info/ ) is a 404.
