The menu includes all user interface options from the General
preferences (now removed from the preferences), toggles for the
collections pane, item pane, and tag selector, and, at long last, a
toggle for recursive collections ("Display Items from Subcollections").
The collections pane and item pane no longer reopen automatically when
restarting Zotero. People might still close them by mistake and not find
this menu, but we'll see how it goes.
