This is awesome. I really love this idea, and love the implementation. Works great and I think will be really useful or at least interesting (can't tell yet).

This is awesome. I really love this idea, and love the implementation. Works great and I think will be really useful or at least interesting (can't tell yet). One piece of feedback-- I'd love a mode where the extension notifies me there are HN threads that pass a certain threshold (e.g. number of upvotes, number of comments, etc.) for every page I visit. This is less privacy preserving, but I'd be willing to make that trade-off in exchange for useful information being surfaced to me opportunistically. Thanks for making it!!
