Widget connector support for Box.com

We're using Confluence Cloud as well as Box as a cloud-based enterprise. An important use case is to embed Box widgets in Confluence pages.

The Widget Connector Macro should support Box embeds. Box has an API to obtain the embed URL, so this seems pretty simple to implement. Here's some documentation from Box for developers.

It seems the same issue was closed in 2014 as unresolved. https://jira.atlassian.com/browse/CONF-23203

Since Widget Connector doesn't work, we're using a painful manual workaround with Iframe Macro. The user has to manually set up the iframe, which is confusing for laymen. Basically, they need to find and copy the embed link and then paste it in an iframe macro, and at minimum define the width and height. Box instructions for embed widget.

Also, the Iframe Macro doesn't seem to support full screen. It should have a field or checkbox for "allowfullscreen".

Please support Box.com with the Widget Connector! It is crucial for the workflow of any company using Box.com for file storage.
