That Slack chart is horrifying because unlike most cases of "features are more complicated than they appear", everything in this chart is user-facing. No Slack user is going to be able to follow all of this to know for sure how exactly their notifications get filtered.
I agree with you. I’m actually quite excited to see that chart, because now I might be able to figure out why I often don’t get messages sent to my phone, but the show as unread when I get back to the computer...
If you're still "active" on the computer it notifies you there and doesn't think it needs to also reach you on mobile. But I think you can set your mobile notifications to notify anyway.
Discord is nice with this and if your desktop goes idle without you reading messages it then pushes them to your phone. It’s one of the best features I haven’t seen in many other products. Particularly as it mutes your mobile notifications when you are on desktop. Which a lot of products also get wrong.
I think the elegance is that all of this logic boils down to a few user inputs (global + channel notification prefs) and overall everything ends up feeling pretty intuitive.
That’s just my opinion as a Slack user but as someone who’s worked on notification and badge systems I appreciate the honing that’s been done here.
