Pro Tips
Use the Reference Guide
The built-in reference guide includes common patterns and examples. Use "Try in Tester" to quickly load patterns for testing.
Organize with Tags
Use tags when saving patterns to organize them by project, purpose, or complexity. This makes finding patterns much easier later.
Test Incrementally
Build complex patterns step by step. Start with simple patterns and add complexity gradually to identify issues quickly.
Use Copy Options
Take advantage of the comprehensive copy options to share patterns with teammates or save results for documentation.
