//    Changed the layout a bit: use group boxes with titles for the two
//    panes, change to use splitters, change the resize proportions,
//    move the "hidden" toggle to the bottom and change its sense,
//    move "insert function" to the right side and group expressions into
//    categorized submenus, reword some other labels to make them more
