In the Editor you can load any project from Template, Public and your own Private projects. To save a Template or Public project as your own, you need to press the Save as new button on the main menu. Then it will be added to your projects as public and you will be able to save any changes you make to it.

Auto Save

The editor will autosave your edits every few seconds. You can see if all changes have been saved at the right bottom bar.
