Pretty decent but missing some basic functions – Working Copy - Git client Review

Works pretty good for browsing source code, which is my main use for this app. I don't do much editing just reading, . Only gave it 4 stars because there doesn't seem to be a way to anonymously update your local copy of the remote repository without deleting and recloning the repository. I can "fetch" new changes but there is no option to "checkout" those changes. There is an option to "merge" whatever that means, but it requires you to create some sort of identity. It currently seems like there is no equivalent to perform basic operations such as "git checkout origin/master" at least not that I can see.
