This project is a simple JavaScript-based molecular editor. It was created because only a few JS-based molecular editors are currently available. The current version is a pre-alpha prototype with a very minimal user interface.
Avogadro2 and the rowan are excellent alternatives. However, this project was initiated as a foundation for future work and experimentation.
