Seriously. This latest major update introduced HUGE load times anytime you switch branches, do a commit, or push or pull your changes. I mean, the new logo is ok, but this software is not. I shouldn't have to refresh the page manually to see the changes that I just pushed/committed, etc. It's a little ridiculous. Whatever you are trying to accomplish with the "fetching older commits" is killing the productivity of this application. Please find it in your heart to undo those changes, so that we might have a functional piece of software that will again be worthy of the title, "Best Git GUI Available"...otherwise, it's just not.
EDIT: I'm on Windows 7 64bit/SourceTree V 2.3.1.0
