One idea that I've been thinking about is an or where it is a app so you get a new file everyday right except the app keeps track of all the files for you. the idea is that anytime you type anything it it basically makes a commit and use so anytime you type something it commits automatically after a quick pause after you stop typing.
That sounds ! Could also create summary titles with for the filenames in addition to their date so you can find what you were writing about easily. Also full text search.
