That's fascinating. I do have plans to add context to one's timeline; for example, to optionally overlay the weather on that day, or major world or local events. That might be helpful in understanding your own timeline entries in hindsight. So the life choices thing is interesting. You're talking about divergence points, or nexus events (there are different terms in different literature/cinema), and charting your world lines, basically. (Some Loki and Steins;Gate would be recommended watching.) I am not sure how to do that, but would like to figure that out...
