Yeah it should. There is a slight url mismatch in this particular case. The HN Api response is returning the url without a trailing slash and hence my code is rejecting that result. I will try and fix it. This was just a basic version coded up in a few hours to see if people find this useful at all.
Yeah. It's just a single API call and few lines of javascript. I took more time to create screenshots and add descriptions on the chrome store than to code it. Even I find it useful personally and that's why I built it. But it doesn't seem to have piqued HN users' interest or maybe just didn't get enough visibility.
