We have all bits together to enable default menus now. The attached
changeset adds deafault menus to all figures. Of course they are not
shown for the gnuplot backend.
All menu entries should work, except for the Help menu, where I have
added placeholder for an about entry. It would be nice if we could add
some internet resources there as well (home, docs, bugs, chat(?), ...)
but for that we need a generic browser function which must work on all
platforms.
Before pushing such a change I would like to get some feedback.
