Add-on the ability to embed a video in the document.
If I want elucidation in a document, I should be able to embed a video. This is nice for impressive proposals (your system is sooo close to proposal software; big market!) In the PDF download of the document, perhaps it is just a link or an image with a link.
This is a fascinating idea. One that could be fairly simple to integrate (though we'd need to confirm with our development team). So if I understand you correctly... you're wanting the ability to embed a video URL (or image) on the document success page (or rather the page a signer sees when they successfully sign your agreement)?
If you can please further explain... thanks!
