Customizability of notes collections

The recent addition of collections for notes is extremely useful, but it is limited in its customizability. Two specific items I would like to see added:

1. The ability to customize the length of content shown in the collection summary.

2. The ability to "star" or "favorite" the specific notes that I'd like linked in the collection vs. just showing the first 3 and be able to customize how many are shown.
