Workspaces consist of panels, and you can save space by gathering several panels into a panel
group. The names of all the panels in the group are displayed across the top. Click a panel name
to bring that panel to the “front” of the group.
When many panels are combined, you may not be able to see all their names. If this is the case, a
list of all the panels in the group becomes available. Click the chevron in the upper-right corner
of the panel group to access a panel.
You can display any panel by choosing it from the Window menu, so if you can’t locate a panel,
just look there.
The principal elements are shown here.
