PM1> Looks like a PM who is out of touch with what the developers want. Easy mistake to make.
PM2> Anthropic knows better than this developer. The developer is probably wrong.
I don't know for sure what the best decision is here, I've barely used CC. Neither does PM1 nor PM2, but PM2 is being awfully dismissive of the opinion of a user in the target audience. PM1 is probably putting a bit too much weight on Developer's opinion, but I fully agree with "All of us... have seen UIs where this has occurred." Yes, we have. I personally greatly appreciate a PM who listens and responds quickly to negative feedback on changes like this, especially "streamlining" and "reducing clutter" type changes since they're so easy to get wrong (as PM1 says).
> It's good to think carefully about how you're using space in your UI and what you're presenting to the user.
I agree. It's also good to have the humility to know that your subjective opinion as someone not in the target audience even if you're designing the product is less informed in many ways than that of your users.

Personally, I get creeped out by how many things CC is doing and tokens it's burning in the background. It has a strong "trust me bro" vibe that I dislike. That's probably common to all agent systems; I haven't used enough to know.
