title: Start new feature with existing name using Smartgit
body: <p>When using GitFlow with SourceTree I was able to start a new feature using a name that was once a feature. But using SmartGit it restricts me from doing that.</p>

  <p>Is there a possible configuration flag I can alter so it will allow that or is this definitely not possible? </p>
