title: SourceTree very slow with many repositories
body: <p>I work on a lot of small projects on daily basis and need to switch often.</p>
  
  <ul>
  <li>I have over 50 Git Repositories in Sourcetree.</li>
  <li>Usually 5 projects are open in "Tabs".</li>
  </ul>
  
  <p>Switching from "Tab" in SourceTree is very slow. Sometimes up to 15 seconds. How can I improve this behaviour?</p>
