The sidebar is absolutely unusable now: the branch tree is not aligned as a tree (because of folder icons for branches like "private/someuser/somefeature"), current branch is shifted, etc.
File icons are not as helpful as before (they were red-yellow-green, now they all fifty shades of blue).
Not to mention that I was forced to use an Atlassian account & to login for now reason (unless Atlassian steals my proprietary source code, maybe?).
And I cannot find an option to choose the old UI.
And I cannot find a link to download SourceTree 2.1.
How can I revert to 2.1 now?
