title: Split windows in Emacs -- with Tabbar displaying only active buffer
body: <p>I'm using a split Emacs frame to move my windows into a more convenient state.
  However, there are 2 things that bother me, and I wonder if they can be changed:</p>
  
  <ol>
  <li><p>I'm using tabbar, and all the buffers currently open show on all the window splits. I would like only the buffers available to that current split to appear.
  So if I have <code>somefile.org</code> open in the top split and <code>anotherfile.org</code> in the bottom, I would like only the corresponding one to appear in each of the tabbar lists (top and bottom).</p></li>
  <li><p>I wonder if there's a possibility to configure the mode line to appear only once in the bottom, and refresh it whenever I move to a different window.
  Something along the line of <code>tmux</code>, to those who know - the information is changed based on the windows I'm currently at (although there it's called panes).</p></li>
  </ol>
  
  <p><strong>EDIT:</strong></p>
  
  <p>Regarding point 1:</p>
  
  <p>Say I have 2 open buffers - <code>file1.txt</code> and <code>file2.txt</code>. The first is shown in a top vertical split, and the other in the bottom one. I would like the top tabbar to only show <code>file1.txt</code>, and the bottom to only show <code>file2.txt</code>.</p>
