The Course Tab
This displays the courses that you are enrolled in or teaching. It looks very much the same as it used to.

Gear button: Use this button to customize what courses display in the My Courses module and how they display.

This is very similar to the old set up for doing this.

Edit Mode and the Disappearing Left Hand Side Panel

1. Hide Course Menu: The circled button under the number one allows you to hide the left hand side bar. Then simply click it again to bring it back.
2. Edit Mode: This button is very important in the new version of Blackboard 9. Instructors, Teaching Assistants and Course Builders will be using this button to add content to the course. When Edit Mode is turned off, barring the Control Panel, this is how the students will see your class. When Edit Mode is turned on you will see all of the buttons to be used to customize your course.
