The one killer feature I'm hoping some GUI client implements is the ability to seamlessly search and filter branches by just typing the way most IDE's implement search for symbols or files. I work on large active projects that use git flow and inevitably there are dozens of branches. Sourcetree in particular is slow and painful in this scenario and I would love to replace it. Sublime Merge is looking very responsive and cleanly organized. Great job!
