To add a new scene:

Step 1: In the scenes timeline, click on the plus + icon above the timeline to add a new scene.

Step 2: You can choose between adding a Blank scene, or a scene From template.

Once added, the scene order can be changed if required, by dragging the scene to another position.

When adding a scene from another template with the Templates option on the left panel, click on the View scenes option, and then select the scene you would like to add.

We can also drag and drop a template scene directly to have it come to a specific position between 2 scenes.
