Changes to the toolbar that would actually be useful — allow users to choose the positions of each button they want in the toolbar (preferably by drag & drop); give the option to show/hide labels for the buttons; provide for at least 2 rows of quick tools, and for small and large buttons. Allow the user to decide where the thumbnail and bookmark panes are positioned — left, right, or even below then document pane. I hope the new Acrobat Pro changes to these features are short-lived — they are going the wrong direction.
