FYI: I just added a new toolbar (off by default) to LyX 2.2dev for people working on the documentation. It gives easy access to LyX and LaTeX logos (bug 9626), which are no longer produced automatically if the phrases occur in the text, so you do not need ERT separators anymore to prevent that), and the info and menu separator insets. If there are other documentation specific lfuns which I forgot we can easily add them as well.
