Improvements

Implementing Pattern Type (ie atoms) Documentation

This allows MD docs to be added to the top levels, such as Atoms.

Given this structure:

• _patterns/
  • atoms.md
  • atoms/
    • forms.md
    • forms/
      • select.twig

This will take the contents of atoms.md and place at top of "Atoms > View All", similar to how forms.md is placed at top of "Atoms > Forms > View All".

Fixes

• Improving pattern linking to include View Alls
