 THINGS TO DO
 ------------
 
-** `tool-bar-mode', `scroll-bar-mode', `menu-bar-mode' and
-   'fringe-mode' are modes global to the entire Emacs session, not
-   just a single frame or a single terminal.  This means that their
-   status sometimes differs from what's actually displayed on the
-   screen.  As a consequence, the Options | Show/Hide menu sometimes
-   shows incorrect status, and you have to select an option twice for
-   it to have any visible effect on the current frame.
-
-   Change Emacs so that the status of the items in the Options |
-   Show/Hide menu correspond to the current frame.
