For me, here are the top ones:

1. "Unread Posts Turn Grey"

This has transformed my Hellobee experience more than any other feature I can remember. I love that I can quickly tell whether or not there are new comments to check out.

2. @REPLY

This is a close second. I love that there's now more of a back and forth in conversation now, because of the email alerts. It's made the boards feel more vibrant with debate and discussion.

3. Yellow Bubble

I mostly click on the Yellow Bubbles now. I didn't anticipate that this would be so darn handy! Saves me a lot of paging down.

4. TTC Status

This is super handy now and then, but I haven't been using this as much as I thought I would. Plus, I kind of know most everyone's TTC status at this point.

5. Walls

This is a nice alternative to Private Messages for now, but I am not a big PM sender so I don't use it that much.

Which new Hellobee features have you been useful for you?
