The FITS standard recognizes blank keyword lines and also comment lines (starting with `\'). These features help write the keywords in related groups in an easy to read (by eye) format, for example this output of Gnuastro's Crop program:
With this task, I am suggesting an option (maybe named) `--keygrouptitle') to allow the users to create such titles and subsequently write related keywords in the FITS HDU together under it.
The focus of FITS keywords is mainly for software reading them automatically and that is indeed the major use case. But when they are nicely categorized in such a fashion, people will be encouraged to look at them directly, with a command like the one below, and get a good general feeling of the dataset's meta-data.
