As you start adding shapes to your diagrams, the Most Used shape library will automatically populate with your most commonly used shapes. As you use a shape more often, it will move higher on the list. Custom images and shapes are not able to be added at this time.
The Most Used shape library will store up to 18 shapes, on 3 pages of 6. Click the down and up arrows in the library space to move through your pages.
The Most Used Shape library cannot be removed from the sidebar. You can click on the title to expand/collapse the library, and you can also move the library up/down on your library sidebar.
The library is controlled by your local system storage on your computer. If you clear the cache or use a different browser, the Most Used settings will be reset.
