Is the "Optional Live Preview" used at all?

I have clicked through a few items to see if any have an envato-hosted live preview, I can only see self-hosted live previews.

So does anybody know if this Live-Preview-From-An-Uploaded-Zip-File feature is used?

I have use it in a couple items, but you can only upload static pages (js, html, css files) this means no PHP and no Wordpress, besides if you want to make some changes you have to wait until they review it, so is faster to have it in your hosting.

Yup. I use this in most of my items.

It’s a fast and stable preview ( being on the Envato servers )

We use our own domain with hosting which will helps us in long term to develop good seo and branding.
