[Easy Blogging] Feature Request: Display left menu even when showing external/arbitrary URL pages

I have a feature request for the left side menu in both the regular Easy Mode screens and the Wizard Mode screen.

If possible at all, when loading an external page from an arbitrary URL, can that be loaded on the right side so the menu still shows on the left? This will ensure continuity if we want to include pages that are not part of the Admin Dashboard. Currently, loading an external page loads the page in the browser window completely and so breaks the flow.

Not sure how this would best be done... maybe using iFrame, maybe a lightbox...
