The Layers pane contains each and every Canvas, Layer, and Object. Everything is hierarchical: if you move something up the list it will move above everything else.
The Guides pane is a collection of each manual guide you’ve created, grouped by Canvas.
The Outline pane makes diagramming or mind mapping as easy as typing notes for yourself. With Automatic Layout turned on, your diagram is updated in real time.
The Selection pane makes selecting similar objects super easy. For example, you can quickly select all the red hearts on your canvas and change them to blue diamonds.
