We’re currently working on defining a compact mode experience. I will post more details when we have more to share.
This feature is still being reviewed by the feature team. No decision has been made yet. I’ll keep you posted.
The feature team is still reviewing, there is lots of discussion about this item and I hope to have a decision soon.
Hate to be the bearer of bad news. This item has been declined. There will be no work to hide or remove the reply button.
As many people have commented, a big ask is to help improve how people distinguish between giving a reply and starting a new message.
For that the focus will be on this item. “Better visual delineation between `Reply` and `Start a new conversation`”
