As a developer I am managing over 150 repositories which I need quick access to. The old navigation bar in SourceTree 1.x was *perfect*. The new tabs look really cool and are fine if you have to manage just a few, but when working on multiple repositories at the same time, this can really get in your way.
Could you please consider bringing back the navigation bar as an option (disabled by default)? To me using ST 2 is really much less productive then ST 1.x, but I am "forced" to upgrade because of the security issue announced today.
