- Isaac Gould, you can still assign a highlight palette to a particular notebook, but probably better to keep it as "most recent." For notes, if you are using the "N" key or the "add note" button on the selection menu, the note will get assigned to the most recently active notebook, provided you have at least one notes tool instance filtered by notebook. This makes it really nice if you have a couple different notebooks that you wish to assign to frequently, since you can have multiple instances of notes open and filtered to the respective notebooks, then simply make bring the desired tab to the front before adding a note.
