The traffic graph can already display a choice of IP address, Hostname or FQDN in the table of top bandwidth hogs.
Sometimes hostnames are not that descriptive. In the case of locally-known hostnames (e.g. that have static mappings) there is also potentially a useful description in the config. For me that description is useful, since we put stuff like the staff member name and job title there. Being able to choose to display that description, as an alternative to [IP|hostname|FQDN] is useful. It does not add any extra boxes to the display - just an extra option ins the "Display" dropdown.
In future, if there are more places that "extra data/description" can be found for an IP address/hostname/FQDN then code to retrieve that could be also be added.
Not a big or urgent thing, just something I have code for and find handy:
