The shape library shown upon starting your diagram will be dependent on the type of diagram you chose to start. For example, if you choose to create a flow chart, a library will load containing commonly used flow chart shapes alongside other relevant libraries. You can access additional libraries at any time by clicking on the More Shapes button at the bottom of the shape libraries.
You can Expand/Collapse Libraries in the sidebar by clicking the Expand button.
You can hide the shapes sidebar by clicking the Hide Sidebar button.
If you hide the shape libraries, you can bring them back by clicking the “Show Sidebar” button.
