The Panel bar is always visible on the left, except when Full-screen view is set. It always presents two universally useful tools at the top:
Hand: This is the basic navigation pointer. Choose it to finish the use of any other tool. Specify the Hand tool behavior in File> Options > General > Miscellaneous.
Select: Use this to select a text block or an image to edit its properties, export it, etc.
Beneath these two tools, a customizable set of Panel tools is displayed. Each document can have its own set of visible panel bar tools. By delivery default the following tools are placed.
Bookmarks: Place bookmarks manually or automatically from a heading hierarchy.
Pages: See and work with a set of thumbnails; one for each page in the document.
Stamps: View a customizable stamp collection and place stamps onto documents.
Security: Create and apply security schemes covering password and certificate security.
Clip Art: View a customizable clip art collection and place art into documents.
If you do not see a desired tool, right-click in an empty space on the Panel bar and select the desired tool. Remove the checkmark from any panels you do not need. Click Reset Panels to restore the five basic panels shown above. Here are the remaining choices:
Auto-recovery: Lists files whose changes risk being lost by an abnormal program termination.
Compliance: Test file compliance against PDF/A standards or accessibility criteria. Available in Power PDF Advanced only.
Destinations: Place and manage destinations in your documents for easier navigation.

Two more panels are available from tools on the left of the View bar. These open horizontal panels that appear along the base of the program window. Only one can be open at a time. To remove a panel click its tool again. To modify the height of these panels, drag and drop its top separator bar.
