In this lesson I learned to become more familiar with my workspace and know where to locate the panels, controls panels, status bars, the tools panel, etc by going into depth with what each tool does.
I also learned how to change the interface brightness and how to navigate my art boards. The most significant step of this lesson is saving your work and making sure to reset your essentials.
The navigator tool made sure there was a view of all of the art boards by allowing them to fit abroad on your screen.
