-1. **[Workflows of Workflows](../../../side_quests/workflows_of_workflows)** - Complex workflow architecture and composition
-2. **[Testing with nf-test](../../../side_quests/nf-test)** - Testing strategies for Nextflow workflows
-3. **[Metadata](../../../side_quests/metadata)** - Handling metadata for items in Nextflow channels
