Good to hear you are finding your way around notmuch ! It is really a framework where you are required to design exactly the UI and content treatment you want, but it takes some time to work it out. I find the notmuch approach to email is orthogonal to every other client I have used, where you are constricted to “mailboxes” and it has suddenly made my enormous store of emails a valuable resource, because I can search and categorize it in countless ways.
