If multiple results for a page are grouped together and there are more results than those that are shown, display an additional button to see more results from that page. This allows one to immediately spot if there are additional results and then to navigate to them.
Grouping pages is an absolutely lovely feature and this would increase its usefulness a tiny bit more by providing a hint whether checking for more pages might yield more results. (And by halving the number of clicks necessary to get those results. :)
)
Bing for example has it implemented like this but I'm not sure if the button disappears if there aren't any additional results.
This might be a bit more involved feature if you don't already reliably know if a page has more results. In that case, by all means, please close this suggestion - it's really not that much of an improvement. But if you do know, then it seems like it shouldn't be too much work, so I thought I'd ask. :)
