This does 3 things:
 a) make maximum width wider - i.e. from 960px to 1100px; i.e. won't force to larger, just let's you get wider if you can...;
 b) add request headers and request body when doing a request;
 c) re-organize request and response parts (i.e. url, headers, body,..) into a nice table where all request parts are grouped together and all response parts are grouped together in a table;
 d) notes are displayed with "Notes:" in bold before them;
