Reply in full-sized window by default instead split view.
Show reply editor in full-sized window by default instead split view. Currently it shows the original message on top and has only a small input textbox; the user has to press the right icon to enlarge to full-size. Alternatively: let the user select the default view within the message settings.

allow reply with email trail below the reply text like normal outlook. stop trying to mimic annoying Gmail formats.
