And a final nit on Slack's latest UI change for threads:
- Pop out windows for threads: useful to extract context while working
- Thread sidebar that disappears when you change channels: this is awful. Often I need that context when going to other channels and I don't want to popout something 🙄

What I'd really love to see is the best of both worlds here:
- Give me threads as a hierarchy under the slack channel that is collapsible
- Give me the "All Threads" view in slack to rediscover lost threads
- Continue having custom config of notifications for all threads (and unsubscribe capability)

As opposed to something like Discord which has moved to a model of having threads show up as children under a channel in the hierarchy.

I think Discord's solution is significantly better for quickly finding threads about a specific topic. The drawback is it clogs your channel hierarchy over time.
