It's been talked about a lot, to allow newer sites to hit the 'cool' list, to change the total hits to hits-per-day.

Was this feature built in anywhere?

Is it possible to add a page to Links that will give a list of the top X sites by hits?

That is not really "Cool" since cool is what people are hitting, not agregated hits.

A great feature would also be a "Top Sites Today" and "Top sites this week" list?

These features don't look like they'd be hard, but it would be nice if they were built in, so everyone is using the same hooks -- if not the same code for them.
