An easy one for me is programming. This kind of approach the only way I know how to be able to go back in time and recognize / resurrect your thought process.

An easy one for me is programming. This kind of approach the only way I know how to be able to go back in time and recognize / resurrect your thought process. But there's little thorns it solves all over. Ever experienced knowing you did something X days ago but it's in the past and there's literally no way to go back and look at it? Ideally, it solves that. Version control / history is great if the app supports it, but depending on how it works, "a month ago" might not be available.
