Show subject line when forward and reply to an email Merged

It would be helpful if when you reply to an email or forward an email (not forward as new conversation) if the subject line of the email could be open, rather than having to click to open it.

Currently you have to click subject to then see the subject line of the email.

Whilst it might see just a click, it adds up when you are sending and forwarding so many emails during the day.
