Allow filtering notifications by Participating/Mentioned

[j-f1]

The filter icon on the top left would have all the options it currently does except for “View All.” There could then be a dropdown similar to the kind that’s shown on issue/PR/repo screens. This dropdown could show the owner/repo if you’ve filtered by one, as well as a choice between “All,” “Unread,” “Participating,” and “Mentioned.” The API docs say there’s several reasons notifications are sent. I’d suggest assign, mention, and team_mention for “Mentioned” and author, comment, and state_change for “Participating.”

Brought up something similar in #2065.. as I recall, it's pretty low cost to build and implement. Might have more relevance now w/ push notifications?

Yes! Would be nice to only get notified for things I’m participating in.

Open to review some designs/flows/PRs

Yes!!!! This would be huge. I love how the inbox tab lists summarized activity that I’ve missed in repos I follow but would love to only get notifications for threads I’ve participated in. This and the ongoing work in #2106 are the two things I would most love to see!!
