True, but isn't the "show new replies to your posts" functionality providing exactly that?
On the line you quoted, I was responding to the following part (should've added those lines to the quote, sorry [in other words, I was explaining the importance of "Show new replies to your posts" feature):
Therefore, I think the default setting should be to not add a topic to your watchlist after commenting.
If you want it added, you can click on "additional options" and should manually select the "add to watchlist" button.
It just seems like duplicating the same functionality at the moment?
Not exactly.
- On "Watchlist", you can add/remove topics & boards...
