As a new reader, I would very much like to have a method for marking how far through the sequences I am. A dot next to read articles, or possibly a timestamp of last access could work, as could a button at the bottom of the article labeled "Mark as read" that would display the article title differently in the main sequence page. I feel lost when I hop around on different computers as to what articles I've read and where I have seen them before, and simply saving read articles every time is unsuitable for this.

EDIT TO ADD: Based off of what other commenters have said, I feel like a clarification is in order. What I'm looking for is a way to mark the sequence pages I've read, so that when they're linked to in the newer articles I can tell right away if I've read that particular post. Hopefully, this would work for both backward-linking sequences AND new posts that also link to sequence pages. Perhaps a way to store the URL of a read page, link it to my account, and when that URL is displayed again within LW a new graphic could show up to the side of the link to show that it has already been read.
