My main and daily use case it to look back at the previous day - this is helpful for standups, retros, and so on. I skim through my days (sometimes weeks) to pick up on what I was working on - it's incredible how much "untracked" work is performed that you pick up on. Sometimes I forget who exactly I talked to about something, but just knowing the rough date I can usually find something to jog my memory.

Obviously I am biased, but still!

You can do things like find the point in history where you fixed a bug and go watch yourself debug and put in the fix.

Pretty wild. It makes a lot more sense once you experience getting the value.

Personally I hope Apple adds the feature natively to the OS at some point. They're plenty experienced to build it themselves over there, but maybe having a reference implementation will encourage them to give it a shot.
