[Pharo-dev] GTInspector extension menues with line separators and submenu items

Hi, Is it possible to separate the context menus (built with #selectionAct: ...) in GTInspector extension methods with lines similar to the regular menue building where #withSeparatorAfter is used. Is it possible to have submenues in the context menu items (cascading menues as the world menu). Any examples?` Thx T.
