demerphq, for my part I think it is quite a nice bit for those who like it (yes, I do), and that there is an easy way to override it (for those who don't want to use it). Cudos for the work you and others continue to put into the site.
Looking at it, it seems like that might make an interesting/useful nodelet, showing the counts for each of those sections in the last 24 hours (that had not been marked as checked?), and linking to that section in Newest Nodes. I wasn't sure who to suggest it to, how much work might be involved, or if it would be something people might use, but it was a thought.
