Beamer Note 标题 - 如何使其看起来像普通框架中使用的信息线？

Question

我特别想：

• 删除文档标题。
• 在同一行中显示章节和小节标题，居中对齐。
• 保留灰色配色方案。

这是 MWE，附有当前输出的屏幕截图。

您可以将笔记页面重新定义为如下内容：

\documentclass[notes]{beamer}
\usecolortheme{whale}
\useinnertheme{rounded}
\useoutertheme{infolines}

\beamertemplatenavigationsymbolsempty
\setbeamertemplate{footline}[frame number]
\setbeamerfont{note title}{size=\tiny}

\makeatletter
\defbeamertemplate*{note page}{mynotes}
{%
  {%
    \scriptsize
    \usebeamerfont{note title}\usebeamercolor[fg]{note title}%
    \ifbeamercolorempty[bg]{note title}{}{%
      \insertvrule{0.05\paperheight}{note title.bg}%
      \vskip-.05\paperheight%
      \nointerlineskip%
    }%
    \nointerlineskip
    \vbox to .05\paperheight{\vfil
      \begin{minipage}[t]{.48\linewidth}
        \hfill\insertsection
      \end{minipage}%
      \hfill
      \begin{minipage}[t]{.48\linewidth}
        \insertsubsection\hfill
      \end{minipage}%      
      \vfil}%
  }%
  \ifbeamercolorempty[bg]{note page}{}{%
    \nointerlineskip%
    \insertvrule{.95\paperheight}{note page.bg}%
    \vskip-.95\paperheight%
  }%
  \vskip.25em
  \nointerlineskip
  \insertnote
}
\makeatother

\setbeamertemplate{note page}[mynotes]
