Likewise the other Notebook Bar MUFFIN modes.
For now ONLY writer, calc, impress and draw have notebookbar layouts, but it is planned to make the layouts for ALL LibO apps/modules.
Confirmed. And this is *in Writer*, Andreas. Opening an .odm file in Writer makes it so the user interface options are unavailable, as well as macro recording. Opening an .odt file enables both.
