To compare design changes you must first have some changes to compare your new changes to!
Once you have made a change, follow these 3 simple steps:
1. Inside your project, click on the art board that has previous change history.
2. Once at the art board level, you will see Design, Compare, 3D, Original options.
3. Toggle between these options. In this example we are using compare to show a side by side comparison of the two mobile designs.
