Custom annotations for activity view on profile

Problem to solve

This is a proposal to add custom annotations to the activity board on your profile page. It would be a way to add some personal information and flair to what is otherwise a list of events:

Further details

The activity board is such a great feature, showing where you've spent your time and what you've worked on. It would be cool to define optional events on specific days, whereupon they get a colored border and you can click on them to see what happened then that's relevant to that person.

Some ideas for annotations could be:

• A first day at a new job
• A super busy day could be labeled "Game Jam 2018"
• A day with no activity could be labeled "Wedding day!"

Proposal

What does success look like, and how can we measure that?

(If no way to measure success, link to an issue that will implement a way to measure this)
