Feature request: Along those lines, I was trying to find an article (using algolia) which discussed different names for AWS service names confusion and it was useless for that purpose (given search terms I tried). Since I always clear my browser history I couldn't see the links that I had visited.

A nice feature would be if there was a way to note which article links I clicked on or which comment threads I have visited. (If I comment then it's easy to find but I read more than I comment). That way I could just browse back that history and could have easily found that article that I was looking for.
