Every time you use the Save button in your Project, a new version of that Project is created. A version is like a snapshot of your Project captured at a certain point in time.
Previous save versions can be restored at any time which is useful if you've saved a change you didn't mean to or if you'd like to experiment with an idea without worrying about losing your current version. You can learn more about this in Restoring a previous save of your Project.
The Save button in the top toolbar will change states depending on whether or not there have been one or more saveable changes made.
If a saveable change has been made, the button will be pink and labelled Save.
If your Project has no changes to be saved, the button will be greyed out and the label will read Saved.
It is good practice to save often to ensure each version carries smaller iterative changes. This means that fewer of your changes will be lost in case you need to restore a previous save.
Saving a new Project version
1. Go to your Project
2. Make one or more changes to the content in your Project
3. Save your changes by selecting Save in the top right toolbar
You'll see a popup confirming your changes were saved and the Save button will change to Saved.
