- Robust Configuration: All project configuration issues have been resolved, including security improvements, window sizing, and proper error handling
Users can now drag and drop components from the palette onto the canvas with full zoom, pan, and selection capabilities, while enjoying a much more professional and polished visual experience. The immediate focus should be on implementing the Properties Panel to achieve a minimally viable product for schematic design. With proper focus on the prioritized action items, the project can progress through the remaining stages and deliver a professional intercom system design tool.
The project demonstrates excellent architectural decisions and modern development practices, providing a strong foundation for continued development. The main challenge will be implementing the wiring system and advanced component interaction features while maintaining performance and usability.
