What's an editor?
The editor is a drag-and-drop interface that allows you to create content that you can then publish to your application.
How to use the Editor
Click on the palette on the left and click-and-drag a component, like a button (Element), header (Text), or card (Container) onto the canvas. You can move elements around the page by clicking and dragging them. Use the toolbox on the right to modify each element.
