豆瓣评分筛选 is a Chrome add-on developed by mikertan that aims to provide a rating filtering functionality on the popular social platform, Douban. As an avid Douban user, I have always wondered why there was no option to filter content based on ratings. Recently, I came across this add-on that brings this much-needed feature to certain pages on Douban. However, it seems to be limited to only a few pages. I couldn't help but wonder why this useful feature isn't available on the movie homepage as well. Nevertheless, this add-on offers a convenient way to filter content based on ratings on select Douban pages.
