There are few UI's that I hate more in the world than SourceTree. That pile of junk has cost me so many hours of life trying to support the developers in fixing a thousand weird issues.
What exactly were the problems? I have been using it since like forever and have not run into any issues at all. Granted, like I said, I don't use it for any hard-core stuff.
No, please throw SourceTree into the garbage can.
