I've brought a similar suggestion up before and got shotdown, but this time I'm gonna make a convincing case.

I know I for one could REALLY use a favorite threads section. There are some threads that are unusually chock full of useful information and that I will refer back to many times for months to come. I can subscribe, but it'll just fall to the wee bottom of the subscription list as I add threads. If I could add it to a "favorites" list, it'd be right there whenever I needed it instead of having to go searching for the darn thread every single time I needed to refer to it.

What do you think?
