My pain points with git are the detached head states (so puzzling) and basically everything that concern submodules (very brittle.) Anything about undoing commits, going back to a specific version of the code is less painful but I almost always have to google for it because that are not daily operations and I can't reliably remember them. Maybe that would be easier if I used a GUI instead of the command line. Anyway, a simplified git with only basic functionality and dead simple error messages AND part of the standard git distribution would be very useful. After all git does a lot of things but I'm using only a core 1% of it. Even after 10+ years I reliably know only the basic clone, add, pull, push, checkout, branch, commit, merge, rebase, log, diff commands. I have to google everything else, even how to track a remote branch. It's checkout -b but Gould I also fetch and pull it before? You got the idea. And it should be about files, directories and branches, the stuff developers reason about.
