In the free Adobe Acrobat reader, for Windows 11, have the right margin tool bar default to HIDDEN when opening a PDF. I never use it, it takes up screen space and I want to see my PDF content in full screen when I open. There should be a user preference to have it hidden. FYI, clicking "Remember Current State of Tool Pane" in Preferences does NOT solve it.

Your patience and understanding are greatly appreciated.
