Pin or Unpin the Main Header
By default, the main menu bar displaying all workspaces will be visible. To hide the main menu bar, click the "Pin" button located in the upper right (circled below)After doing so, the top header will disappear from view and give you more space to focus on your designated work/task. The top header and all workspaces will still be accessible by bringing your mouse up to the top of the screen, where you can navigate to a different workspace or re-pin the header.
