HI, can I suggest to implement a pages preview in the pages panel? Even more, i suggest something like this website : http://work.co
When you click on the logo, pages are being displayed with a thumbnail grid in a really cool and intuitive way. I think this feature can easily be created by your awesome team. This will allow users to create complexe website and always have a bird view of “everything”.
I think of Adobe Indesign Preview Pages or Illustrator Artboards approach as main references.
Hope that you like the idea and interaction suggestions.
