I'm Tim, a dev at Atlassian. I just thought I'd chime in to let you know we are absolutely taking up the reins on SourceTree again! In fact, we're in the process of growing out our team. You can read a little more about it on the ST blog from earlier this year: http://blog.sourcetreeapp.com/2015/02/25/were-just-getting-s.... We are aware of the performance issues affecting Windows users with certain repository shapes and have our backlog prioritized accordingly.

I haven't had much of a chance to play with GitHub Desktop yet, but it can only be a good thing for the users of all Git clients - nothing like a bit of healthy competition :) However, SourceTree's focus will remain on providing the best possible experience for professional teams using Git (and Mercurial).
