I can manage pages with a preview of my chosen frontend (toolbar/browse/contents)

[djay]

User stories (as an editor...)

• I can Login into the admin ui and see a preview of a private pages (pass auth token) #6
• I can Select which frontend to view the current page #7
  • maybe just enter url at login
• I can Browse on the preview, then the toolbar should change based on the page #8
  • E.g. One one page you might have permissions to edit, on another page you might not. Or on one page there might be workflow, but another page with a different content type might not.
• I can browse content on admin UI and preview is shown (e.g. Select view on contents view) #9
• I can add a page and be editing it in the preview #11
• I can remove a page I'm viewing and it will disappear #12
• I can see simpler management views (contents/history etc) without header/footer/search) #10
  • like quanta design
• I can see an admin UI error message overtop of the frame #45
• I can browse content even even if i don't have permission to add (volto bug) #46

Out of scope

• I can use the adminUI without any reloads #55
• if I add a page and then cancel the page should not exist

Technical

• Shadowing/ making an addon to remove the existing block editing.
  • Put in iframe to show frontend
• Ensuring we are logged in to edit mode
  • Dealing with the permission of tokens
• Create a basic example frontend - nextjs
• Deploy a demo server with CD.
