• Organize your patterns into categories — assign them right in the editor, sync them across devices, and manage the list anytime. Deleting a category never deletes your regexes.
• Start from a template: 14 ready-made patterns — email, URL, UUID, semantic version, and more — each with sample text included.
• A cleaner library: sorting now sits beside search on iPhone, and the Mac sidebar is simpler than ever.
