It sure would be cool if the names of people on our friends list were in a different color in the thread lists (the same way our own names show up in red). The people on my friends list are folks who frequently offer great advice and otherwise have worthwhile things to say so it would be great to be able to identify their posts more easily while jumping between various forums and threads.
I am aware I can see posts by my friends on the Activity page and that's very helpful, but expanding on that idea would be even better.
Just a thought I wanted to throw out there ... I realize it may or may not get added to an already long list of other ideas being considered.
