Yeah but I'd need to click each of them, thus the request for that feature.
I vibe coded the shit out of a Chrome extension that does that while waiting on CI/CD. Go read the content.js to make sure I'm not hacking your shit, download the repo to your computer, enable developer mode in chrome, "load unpacked", point it at the directory with those files, and enjoy your tool tips.

Edit: Took 18 minutes.
I like how the current form is close to the real HN experience without onHover cruft.
