MenuBar, TabTrinket, Separator, Spacer; ledger correction on ListView MenuBar covers all three types that build a bar, and leads with the thing that catches people: a menubar is a TOP-LEVEL object adopted as the connection's chrome, not a child of a window. Also that every item raises `command` whether or not it has an action= -- one without gets a generated cmd.auto.N and that is what arrives -- and that `&` mnemonics are menu-only, with && the escape. TabTrinket, Separator and Spacer complete the simple end. Two corrections came out of running them rather than reading them: a separator does NOT take its direction from the box it sits in (it is horizontal until told otherwise, so an hbox needs orientation=vertical), and spacer has width/height for a fixed gap as well as stretch for an elastic one. ListView's appearance section was wrong. alternate_rows and ledger are the same switch -- both write one field, and the paint path bands with the ledger colors either way -- so they do not combine, and `ledger !alternate_rows` comes out off. The page now says so and points at ledger as the name to prefer. Every executable example across all fourteen pages was run against the real registry: 41 clean, 2 deliberate error demos, 5 structural skeletons left elided on purpose.
