I built https://notedcode.com a while ago. It sets comments in any repo on GitHub or Bitbucket alongside the original source, and allows you to add and share further annotations, keeping them alongside the right section of code even when the code changes.
This is a lot more difficult than you might think. I spent a fair amount of time implementing the solution to keeping the annotations in the right place when the code changes.
No idea really. I made it quickly this morning, and I'm trying it out today. It does make it easier to see whether a bunch of commands were performed at roughly the same time than a digital display.
Your advantage unfortunately obscures other useful information.
My [zsh] prompt displays the exact time down to the second on its own line. I just scan up looking at the time to see if the hours match or minutes... But I still have the ability to know if one was 3 minutes 33 seconds or one was 27 minutes 10 seconds within that hour/half hour.
