A mechanism to switch on/off an overlay to show the slots area and their machine names
Examples:
Some knobs (like Storybook) to change the preview values which are acting like the patterns fields forms:
The slots overlay is easy to do un preprocesses, pattern preview by pattern preview, the 3 examples are not mockups but real screenshots of a 15 minutes POC.
However :
For the props knobs, it seems tricky. Maybe an AJAX request to a renderer endpoint which send the updated HTML markup, which will override the content of the preview area.
Yes, some new features on the library pages.
No, it is safe.
Project with overrides of the library pages templates will not see the new fetaure, but the pages will not break.
