A typical SE answering screen would be something like
While typing moderate to long answers I have often found myself
scrolling up and down to see the rendered answer and/or
expanding the answering box to review the whole answer's big picture albeit at the expense of rendering space.
I was wondering if during writing an answer, the screen layout could be simplified to maximize answering and render space. Maybe something like...
The sidebar contents (related questions, blogs, hot network posts, etc. on the right, website links at the bottom, the exchange options on the left) as well as the original question could be optionally hidden. Any changes to the question while answering could be communicated as a notification.
Such a layout would really help writing answers, especially on laptops.
Is there already a way to achieve this? Are there any hindrances to such a layout being promulgated in SE?
