Starring subscribed topics/mark as important

So as I've used the forums more, I've realized there's basically two 'sorts' of topic subscriptions I have, important ones (auctions etc) and ones where I'm just mildly interested in following the conversation (like suggestion topics.) It would be useful to be able to mark the topic subscriptions I really want to pay attention to. They could then either be displayed in their own list or just mixed in with the others as normal, but with a star or something else to mark them.

This wouldn't have any effect on the actual alert function of the subscriptions - it would be for organizational purposes when viewing the list.

It would also be useful to be able to unsubscribe from things from the subscriptions list itself.

Labeling topics as important would be pretty useful, yeah!  I have the same rough categorization - I have auctions etc that I really want to keep track of, and fun stuff that doesn't matter that much, and it'd be nice to be able to quickly find the important ones on the list even if they're a ways down.
