Put the "Start a new conversation..." box at the top
In Teams Channels, it's way too common for users to start a new conversation when they intend to reply to an existing conversation. Move the "Start a new conversation..." box, and the formatting & submission icons, to the top of the Conversations window. Keep the latest conversation/reply at the bottom. The idea is to create some separation between the "Start a new conversation..." box and the "Reply" link that sits at the bottom of existing conversations.
There was another thread about this subject, and it was "in progress", what happened?

Or maybe just a "start a new conversation" button instead of text box. SOOOOO annoying when people dont use the reply button

I had the same idea and totally agree. With such layout the probability of an accidentally start of a new conversation when a reply was intended is much reduced.
