Watch out

• ⚠No official Windows support (only Linux/macOS, WSL for Windows users)
• ⚠Limited community adoption compared to Jupyter ecosystem
• ⚠More complex installation process due to JVM requirements
• ⚠Scala expertise required for full platform utilization
• ⚠Browser compatibility primarily tested with Chrome
• ⚠Limited programmatic notebook execution capabilities
• ⚠Debugging Python through JVM can be challenging
• ⚠Smaller ecosystem of extensions and community tools
