1 - I don't know if this is a suggestion or a bug, but when you are in the main Feature: Forums section, it shows 0 posts in both Suggestions and Bugs. There are posts there, however, so that should be fixed because it kind of makes things look dead. (It's NOT like this in all sections of the forum, though, for example Site Updates seems to work fine).

2 - When you subscribe to a thread on Kumos, it gives you notifications for each and every post. This is a lot more events than on legacy, and honestly, I only need one post until I go back and post or check to see what's happened since I was there last. All the events now are.. a lot.

3 - There's no 'jump to newest unread post' button, and no way to tell if you're read or haven't read a thread yet. PLEASE implement these, they're just better for quality of life.

I can see a little tiny vertical line next to threads with unread posts but a) it looks more like a visual glitch than something important, and is very easily missed, b) it overlaps with user borders, c) it's not a link to the newest unread post. As said, that's a really important/helpful feature.

You can see in this screencap that I'm caught up on the Kumos Speed thread (no brown line) but everything else has that little line. Legacy had a tooltip on hover for the "go to most recent unread post" link, so you knew instantly what the button did, and the shape of it (speech bubble) also felt more intuitive.

I've also noticed Kumos is missing an indicator of when you've commented on a thread. I'd love to have that back.
