Would it be possible for the reply element to remain fixed to the screen?
It is not possible to see the reply being composed
side-by-side with the previous messages. We often receive complex requests with
multiple points to reply to, and in an e-mail client we can just slowly scroll
down the previous messages while entering a reply in a separate window.
Constantly scrolling up and down while composing a long reply wastes a
significant amount of time.
