Add the comments section to an external window of any email (composed or existing)

It would benefit our entire company as we use the comments section for notes to ourselves and others. Also, it would make the comments section cohesive across the board regardless what window you are in while using Front. Attached is a screenshot of what I mean. Basically at the bottom of that external window have the comments section. As of now, we need to go to the draft section within the app or hit send then go to the send box and add it there.
