Thread tree view

I'd like to keep track of threads in a tree view.  By scoring the references 
line of the threads original post, I can make sure that article bodies of all 
new posts to the thread are downloaded.  So far so good, all the threads' 
article bodies are present in a tree view.  But there is no way to set apart 
the ones I've already read from the newer ones unless I mark them read and 
then have to enter the group showing all the groups' read articles, not just 
the ones from the thread I'm interested in.  Do I have to use the sticky 
tags macro and tag the ones I've read or is there a simpler solution?
