Please add a global setting in Adobe Reader that prevents the Bookmarks Navigation Pane from automatically opening when a PDF is opened.
Currently, this behavior depends on individual document properties, which means users must manually close the pane every time or rely on inconsistent workarounds. This is disruptive for those who rarely use bookmarks.
A simple preference option (e.g., “Always hide Bookmarks pane on open”) would greatly improve usability and workflow efficiency.
Thank you for considering this enhancement.
