Right now, you'll see only three results. We'll look at refreshing, but in answer to #2, we're also looking at putting this more directly into Google's search results.

I think having block options directly on Google's search results is the right long-term answer. But this extension lets people clean up their personal results while sending block data to Google that we might be able to use as a signal to improve overall search quality.

Thanks to everyone at HN who poked us by asking for this, by the way.
