It probably exists or someone made it before but I couldn't find it so I created one myself. I also noticed people check each other's profiles often so this might come in handy.

Screenshot of the usage (ignore the red arrow it doesn't come with the extension): https://imgur.com/a/gvJ93ne

This Chrome extension does one simple thing. If you want to check the user information listed in the profile including username, creation date, karma, and about. You just need to hover over the username. I was clicking on users before and it was a waste of time I thought and created this simple extension.

The delay is set to 0.5 seconds so when you move your cursor over users while navigating you don't send requests to the HN by accident.

Cheers.
