Super clear analysis and presentation of the core problem in group messaging today. Your visuals made the post so easy to read.

I’m not sure the conclusion applies for all cases. It may too easy to get lost in a thread behind an attachment.

Once I got used to it, iMessage’s UX has held up best (posting twice — once in focused thread and again in main thread). Not sure actual post has to happen in both places, but at least the activity should, otherwise there’s too high a risk to lose something or to have context switching set too high a friction bar.
