Going through notifications one by one is tough when there are a lot of them, because I’m constantly context-switching in my mind. It would be nice to group notifications by project and/or team (ideally both!) to understand the bigger picture of what’s been happening.
For an example, Slack does this really well if you use the “All unreads” feature. It groups all your messages together in one pane, but they are grouped by channel and you can minimize/maximize the groups.
