Issue: Red link (page not found): More obvious link to new page editor (and maybe load the editor directly)

As a related idea to suggestion #5392, in 4.1 do you think it would be possible on red link pages, provided that the person has permission, for a "create this page" (or start this page, etc.) link to be added beneath the current 'could not be found' error message?

It would be super cool if clicking the link would dynamically load the editor without a page refresh, just like XenForo 2 loads in the editor for 'Quick Thread' (source). I'll attach an image mock up (based on XF1 styling). Even if this part of the suggestion isn't realistic, just adding the additional link (or button) below the current phrase would be welcome. The added link would be consistent with category pages which link to the editor: "Edit this page to add more relevant text."
