  def caveats; <<-EOS.undent
    By default, a splash screen is shown on startup; this causes the main
    window not to show until the application icon on the dock is clicked
    (Cmd-Tab application switching does not appear to work).

    You may want to disable the splash screen in the preferences to
    solve this issue. See:
      https://github.com/wbsoft/frescobaldi/issues/428
