It looks like you mindlessly associate a CLI with a poor -- or suboptimal -- user experience. In fact even your choice of weasel words conveys the idea that you want to mindlessly push an irrational belief in spite of not being able to provide arguments to support it. The truth of the matter is that git -- or any other VCS -- operated through commands that change the current state of the repo. The command line interface excels when the user wants to run commands. Any GUI developed for command line tool will end up doing nothing more than replicate what the CLI already does, and will do so poorly.
Put another way, Git is a process that can be rendered pictorially. Words (i.e., CLI) are a less intuitive abstraction.
Pardon me for stating the obvious :)

Understanding that git reset --soft moves HEAD but doesn't change the staged snapshot or working directory, whilst --mixed updates the staged snapshot to match the commit but doesn't touch the working directory was very useful. And knowing that reset --hard updates both staging and the working directory to the commit was where I suddenly "got it".
