Ask HN: Is there a browser extension for tagging HN users?

I searched but didn't see anything relevant, either here or on https://www.hnsearch.com/apps

One of my favorite parts of Reddit Enhancement Suite is the ability to tag other users - especially so I know who else is a lawyer and who just likes repeating things they saw on Law & Order.

But I'd also like to know more about other users and seeing who seems to have expertise in other areas or who works for X company might help me wade through a lot of the great content I might otherwise miss.
