title: Emacs keep opening lots of buffers (Clojure)
body: <p>I'm a beginner in Clojure and for some reasons I decided that Emacs would be a good choice, because of its usage among the clojurists.</p>
  
  <p>But something that's really anoying me is that Emacs (for working with Clojure projects) opens a bunch of buffers. i.e, when I click "Read a directory to operate in its files" and select the lein's project root, I need to select myproject.core.clj and Emacs keep all the super dirs openned in other buffers. When compiling with cider and working with many clj files, it's painful to keep on alternating through all those buffers.</p>
  
  <p><strong>How can I limitate the numbers of buffers that Emacs leave openned?</strong></p>
  
  <p>(I know C-x k)</p>
