Yeah and this is what the list type does not provide and what I wrote above, or tried to explain above
There exist list types where you can add a category headline, but without any dropbox. Only fixed text you define once.
And you can add owsbelow the headline then. But even the friendslist list type does not provide that and one would need to overwrite all code from the scratch!
Or you would need some totally new UI there which replaces the current one, or is shown next to it (movable frame).
Both a lot of work for a small benefit (category could be added to the note e.g. already as free text; it's just not sorted below the category then, that's why the column wa smy idea to circumvent that more easily), but perhaps someone wants to take the challenge (with the column e.g.).
Edit:
The later addon with the new UI already exists, including grouping and color for the groups of your friends:

You maybe should ask there for more features if you want others.
