One small thing this is missile is some sort of indicator that shows you which threads you have posted in yourself. Its a very small problem but it makes it easier to follow up on multiple conversations without making many bookmarks.
You know about how under the login screen you can click on My Posts and My Replies to see what you've posted on right? Just checking.
I believe you're saying it would be nice to look at the forum posting list and tell which one you've replied in so you don't have to check out a thread again unnecessarily, or to specifically check on a thread. I use a combination of bookmarks, the My Posts/Replies, and the icon indicator on new posts/replies to keep track of such stuff. But you can't watch a thread like you used to be able to (removed for some reason).
I do agree a way to check on all the dev posts would be great.
