The use case is that I go to the top page of a huge thread, the only new messages are under a "Continue this thread" link, and I want the widget to tell me that there are new messages and help me find them. I don't want to have to open every "Continue" link to see if there are new messages under one of them.
Ah. That's much more work, since there's no way of knowing if there's new comments in such a situation without fetching all of those pages. I might make that happen at some point, but not tonight.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
Notes for future OT posters:
1. Please add the 'open_thread' tag.
2. Check if there is an active Open Thread before posting a new one.
3. Open Threads should be posted in Discussion, and not Main.
4. Open Threads should start on Monday, and end on Sunday.
