I know I've suggested this before, but I'm really missing the little black dots in the center of the envelope that marked the threads that you've responded to. Sometimes folks don't use the most descriptive subjects on their threads, so it's hard to remember what a thread was about, but you do want to see if anybody reponds.

I know you can check in your post to get email when somebody responds, but I'd rather not clutter up my inbox. Is there another way? If not, is it on the list?

Certainly... along with many of the other little features we all came to enjoy. You should see them coming back little by little. We've already made several changes based on feedback and will continue.
