Things that are GOOD about the new Forum SW:
I think I am especially appreciating the way the new forum SW handles "tracking." Specifically:
"Tracking" status does what I want it to - adds the topic to the list of things that show up in my "unread" list.
The "track a topic if I spent N minutes reading it" is useful and reflect some of the ways I use the forum - I used to "lose" things if I was read them on a non-keyboard device and it wasn't convenient to enter a reply at the time.
It's easy to change around if a topic gets boring or heads in a direction that I'm not interested in.
