Show HN: I built a bookmark to fix Amazon search

As a heavy Amazon buyer, very often I am frustrated by Amazon search results.

For instance, with so many fake reviews on Amazon, I seldom care about items with no or only a few reviews. Hide them plz.

Also, pretty often Amazon shows me stuff whose names don't even match my search, come on!

Why Amazon doesn't allow me to set how many items per page? I don't wanna go through pages of stuff :(

Price Low to High is a joke! So many $0.01 items with $10 shipping fee!

I am writing a bookmark to fix all of these. Give it a try at heartthese.com and let me know what you think.
