For newsgroups, I have noticed that headerview doesn't show Newsgroup name - While ordinary email shows fields for "From", "To" and "Subject" - Newsgroups only show "From" and "Subject" - It would be nice if also "Newsgroups" were shown on a line. However, it was harder than I thought - Searching through the source, I found my way to src/headerview.c:222 , which suggests that msginfo->newsgroups are NULL even when messages from newsgroups are viewed. While "Newsgroups:" are shown in the message headers, I still believe that it would be nice to have the information in the headerview too.
