There is currently a field called "Content encoding". This does not relate to the Content-Encoding header, but is the encoding for the content.
It would probably be clearer if the field was renamed "Charset". Agreed? Also, PUT and PATCH methods require the Content-Type to be specified. At present this has to be done via a Header Manager or via the MIME type if a file body is used. Perhaps we should add "Content-Type" to the GUI, e.g after "Charset" (if renamed) ? The "Post Body" tab actually applies to PUT and PATCH as well, so should be renamed. Perhaps "Content Body" ?
