title: Interactive terminal in VIM
body: <p>I'm using Vim for editing source code, but I would also like to have a terminal embedded in vim's window (just like in Kate, you know). </p>
  
  <p>Now I have seen the vimsh plugin that turns a vim buffer into an interactive terminal, but I don't like 2 things about it: </p>
  
  <ol>
  <li><p>It opens automatically at startup. Can I disable it and invoke the terminal with a special command whenever I wish?</p></li>
  <li><p>It splits the window in two and occupies the top window, but I would like it to occupy the bottom window. Can this be arranged?</p></li>
  </ol>
  
  <p>PS: I'm not exactly a vim guru :)</p>
