EDIT: Nevermind, I managed to add it fairly easily. It's mostly exactly the same as the old recommendations endpoint so wasn't too difficult to reconfigure.
Should now display under Trakt as "Movies Favourites" and "TV Shows Favourites"

Skins can get the notes using ListItem.Property(trakt_notes)

Oops, I should have checked here first...I just added the request on Github.  

Yes, I see "Movie Favourites" and TV shows Favourites" now, and they work fine.

About the notes:
Skins can get the notes using ListItem.Property(trakt_notes)

If I were to add one of these Favourited lists as a Homescreen widget, on Arctic Horizon 2, how would I expose the notes, using that pointer?

No worries!

In terms of notes, not really possible from the user side of things to display them. It needs a change in the skin itself to show them
