Put back the Treeview Navigation

Just updated and noticed the Treeview Navigion is gone!. Checked the release notes and it seems the decision was made to do away with them. This the main reason I love SourceTree and been a faithful user since that feature got rolled out.

Please put it back or at least make it an option that can be turned on and if that is not possible make previous versions of SourceTree with Treeview downloadable. Thank you for your time.
