Git really needs something on par with Mercurial's TortoiseHg - it actually manages to express all the edge cases in a natural fashion, and lets you jump from cmd line to gui and back with ease (it's more of a cmdline tool that happens to invoke gui dialogs).

I've been looking for years to find something like it for git. Nearest I've seen was GitKraken, but it's UI is still horribly opaque, can't invoke from cmdline in nearly the same way, and requires me remotely authenticate (!?) to use it :|
