Good morning!
I had labeled many of my notes in notebooks with the subnote title (not really sure if this was the name for it), but now that labeling section when making notes is missing and has made finding/organizing these notes less fluid/functional.
I have also noticed that it seems like you have to associate every highlight palette with either a specific book notebook or existing notebook (as opposed to having the previous "resource specific" or "palette specific" options. Instead the default looks like "No notebook." Since upgrading I had not noticed this and now have notes from highlighting/reading, etc. that are in this "No Notebook" label(?). Wonder what I can do about this.
