I've loved, especially as a newer online player, the ability to have a tab open to Qvist's card rankings page so I can not only check out how different cards are ranked, but have easy access to each card's wiki page in case I have rules and/or strategy questions -- that is except for the 2nd edition cards (and individual castles and Sauna/Avanto and unlisted $6+ -- Dominate and Conquest and ??). Now I personally don't need it anywhere near as much as I used to, but I think this would be a great resource to encourage newer players to use, especially if the rankings page were even just updated to list the new cards at the bottom so players could both get as much rankings info as is available and link to every card's wiki page all from one place.
Also, six months in, I personally can't wait to see how people would rank the new 2e cards, and would love anyone's opinions on this. Maybe anyone interested could give a list such as Vassal: x, Harbinger: y, etc. where ranking a card x means you would list it between the cards ranked x and x+1 on the current Qvist list?
