this is indeed useful, but what the parent comment is referring to is it also stores with local history outside of git. So you can check both git history for a selection, as well as local history that exists since your last commit.
I use my editor's history heavily, but never needed something beyond the Ctrl + Z / Ctrl + Shift + Z history to access things done immediately prior. If I'm unsure if I'll need some approach in the future, I make a commit. I've become increasingly good at this prediction.
