Please, please allow a feature to DISABLE the bookmarks panel. It is completely useless in most cases but always opens on every new document. I open a lot of new PDFs every day, and EVERY SINGLE ONE pops up with a bookmark panel that is useless and takes up half of the viewing pane, which I then have to close. Truly, it is enough for me to stop using this program and find any other option, even if it has fewer features. This feedback does not seem uncommon when I spent a lot of time searching around for a solution.

Just put an option in the preferences to disable the bookmarks panel, please.
