@bmuenzenmeyer can you provide some additional context here? I can take care of the website.

the thought was to add to https://patternlab.io/docs/advanced-exporting-patterns.html with the new options available on pattern-lab.config in the above linked PR:

• patternExportAll

  • default: false
  • description: if true, overrides patternExportPatternPartials and instead exports all patterns

• patternExportPreserveDirectoryStructure

  • default: true
  • description: if true, preserves the top-level pattern type structure (atoms/, molecules/, organisms/) during export. if false, all patterns are flatly exported to the patternExportDirectory

• patternExportRaw

  • default: false
  • description: if true, exports the pattern's template file instead of the rendered html
