It would be cool if sublime can show different versions of code though a timemachine style with svn or git etc. Besides the code overview slidebar you can add a versions list. click the diff version you can hover diffs or split out a new frame to show the old version of this file.
P.S. I'm not a native Englist-speaking ppl.hope you can understand what I trynna to describe : )
