Conversation Inbox: UI Changes for Reply and Comment

Currently in the conversation inbox, the tab for "Reply" and "Comment" are very near to each other. The only differentiator between Reply and Comment is the yellow box background. Therefore, it is easy be overlooked by users, and users ended up sending a reply to a customer when it was supposed to be a comment to their team mates.

It would be great if there are a bigger seperation for "Reply" and "Comment"

When users are replying to the conversation inbox email, users are not able to see the full details of the emails such as: the full contacts to be cc and bcc, full email title. Users would need to click on "Expand Email Editor". 
It would be great if users could see those information right away.
