Mine's a mixture of bug and feature request.
Currently the thread "feature requests for 1.6" shows the posts chronologically. If there is a reply to a post you can see that there is (it says "Replies:1" for example) and you can click the link to show the reply indented below the post you were reading. But it ends there. Replies to the reply are not shown, you won't even know there are. Those second level replies are only linked/shown at the chronological position of the reply to the original post and shown at their own chronological position. But at this position you usually won't even understand what the post is about.
IMHO it would make sense to have the possibility to sort this thread by threads, so to say.
