When you click on a thread, it's title is highlighted in active conversations, so you know you have read that thread/can watch it. Is it possible to do something similar with posts in a thread? Sometimes I start reading a thread, have to go away (get a life!) for some time and then, when I come back, it is difficult to work out where I had got to in the thread - particularly when there have been a lot of posts in my absence. It's sometimes time-consuming to trawl through the whole thread to work out where I had got to previously.
So, all posts which have already been read could be highlighted in the way the thread titles are in the list of threads, so you just go to the place where you finished.
Pretty please?
