Yes, I was not sure the option was available in the free version or not.
The editor is based on progressive enhancements, which basically means it uses multiple web technologies to enhance the look.
In terms of a developer it would be called a “Adaptive Responsive” page.
If it is a mobile device the mobile page is chosen and then resized to fit the mobile device.
This allows the page to have the same design and look in all devices versus just “Responsive” which pushes the content down the page when shrunk.
The rulers at the top of the editor are in pixels the mobile view is 325 pixels in the paid versions its 500 or so pixels.
The free version uses a 325px iphone 3 screen for the size of the canvas in the editor and then enlarges the page up to fit the screens of larger mobile devices.
The paid version I would have to look up the exact size of the canvas, but I think it is 500px and it adjusts in either smaller or larger directions depending upon users device. The paid version has less scaling and has more screen resolutions programmed into it, and the larger canvas makes it easier to use.
Typically the ipad is about 800px and and the scaling is not drastic.
I hope this helps.
Any positive feed back you can leave for the plugin is always appreciate.
