Customize “updated” links

I would like to be able to change settings to the length that a site is marked as “updated” in my links section. It currently seems to be rather short. I’d like to see that be more like 24-32 hrs and I’d like to be able to sort them by the latest updated.
Just some thoughts on how the links could be improved… It isn’t a big deal as I’ve never used the features before switching to WordPress, but can see how they could be more useful to me now. 🙂 Thanks for the great work on this folks.
