In reply to Jon Ang.

I'll illustrate one convoluted item which needs documentation, or more likely refinment

Use case: make a Pattern.
User (with relevant rights) lays out some blocks in the editor, and wishes to make them into a pattern for re-use.

How do they do this?
Currently it's not self explanatory. There's a menu item called "Add to re-usable Blocks" which is a similar but different (abandoned?) feature. There is no "Add to / Export to patterns (json)" here.

If a user finds the code view and copies the text they'll need to unescape it. Most online tools will throw an error at the input ("invalid JSON"). So teh best option is to actually "Add to re-usable Blocks" then manage reusable blocks then export as JSON, then add into a file for later re-use.

I think that process is less than sleek or self explanatory considering Patterns are such a big headline feature.
