Do you use `git stash`? I don't understand your workflow, do you commit to keep a log of your whole line of thought? As in: with your mistakes or failed designs/approaches being backtracked (overwritten/removed, etc.) and keeping an immutable sequence of your line of reasoning? For me, commits of work in progress are only done on my development branches before I want to push to a remote to save my work in case of my computer failing (or getting lost/stolen, whatever force majeure), I usually write a "WIP: <what's been worked on>" message that I will squash later on when I have a meaningful commit.
