Half of my interactions with the Slack UI are desperate attempts to not accidentally lose notifications, particularly through threads. "Mark Unread" is the most frequent command I use I think.

it's wild that in 2022 we don't have better patterns for this

I do think there are relatively easy things slack can do to improve this experience, but I also think that notification and task management is unsolved and mostly unattempted

Yep I missed discussion about an important meeting today because it occurred in a thread in a channel I don't normally talk in. I like the idea of threads but I feel like you miss so much of the conversation if you're not actively looking out for them.
