Not necessarily for settings page, but I didn't see another post for feature suggestions. Also not sure if this has been suggested before.
It would be cool to have a total worth amount, kind of like SteamDB has for steam games, but for all the games in your collection. They have the lowest of all time price, and also the current price (add up lowest price on official stores for all games). This isn't super important, but is definitely something cool that I think would be cool to see!
