Currently in the Newsletters view there are 2 tabs: Active and Unsubscribed. I would like an extra one, either "Archive" or "Not Newsletters" or "Other"...

Problem is many senders/threads are categorized as newsletters whereas they are not (for instance delivery notifications or login codes), therefore cannot be unsubscribed so they still appear in the Active list, polluting the list of actual newsletters.
I know we can send email headers to Proton so they improve their detection but there should be a button to mark the selected "newsletter" as "not a newsletter"
