Thank you both @dax and @davidkingham. That looks like what I want and I appreciate.
The only small qualifier (not a big deal) is that I’d prefer an option for “Watched” rather than “Bookmarked”. My assumption here is that they are two different, though related, concepts (presumably where Watched is a superset of Bookmarked). Not sure if I have that right but I might choose to watch a topic that I don’t care to Bookmark, whereas if I bookmark a topic I assume it is watched automatically.
Not sure…off to read some more on these two terms 
Thank you both again.
