Fair enough. Didn't mean to come across as insisting. There was much debate about the term track. Project is closer, but has problems also. Cheers.
Better to slightly misuse/expand an existing know term like projects or notebooks to cover more than it does now, than to invent a new term that covers all the meanings that apply, but whose meaning is initially unfamiliar to people.
E.g. "my way is da best, you should do WHAT I SAY"
Though the one I listed is the first lemma.
