The Babylon.js Editor is also available as a desktop application.
Note: It is highly recommanded to use the desktop app as you'll get access to the local file system to save your projects.
This will allow you to continue working even in offline mode and save projects directly on your local file system instead of using OneDrive. Using the online version, the editor will have to save projects
on OneDrive as it doesn't have access to the local file system.
Also, when an update is available (new features, bug fixes), you'll get notified and the editor will download the new installer for you.
Note: in some cases, updating the desktop application can fail, you'll have to re-run the installer to finalize the installation
