Doing the one thread at a time thing, yes. It's faster than using one tab, because I only have to load the topic list once, and not every time I go back after having read a thread.

Actually, in Chrome, it doesn't reset the hover thing until your mouse touches the page again. When closing a tab, the cursor is at the top of the window with all the other tabs, and therefore the underline won't reset. I've actually tested it through Chrome's Inspect Element thingy (where you can edit the html of a page) and it works just as I would've imagined.
