Not trying to knock the idea, I just can't imagine branching or reverting or being curious about the history of a to-do list. Maybe it could be cool for statistics over time.
But I'm really curious to hear how you're using it!
they can be ruthlessly minimal.
The intermediate note-to-self stuff, the reference material, the stuff that was cancelled, all can be deleted.
But you have the peace of mind that you can get it back.
This might be especially important if it is a text file you run your life with.
My neighbor needs the name of the plumber we used. What was the amount of the bill? When did I order xyz last? What was the size of the wiper blades of my car?
But how do you look that information up in git?
Pros: pushes only the differences, keeps history, can be rolled back, works offline (push fails but commit works), offers a time log of changes.
Commit messages are not needed really - the timestamp is enough and rolling back is only for exceptional events (e.g. accidentally deleting important stuff, etc.).
Hosting private repo on gitlab solves hosting.
