I think it would be very convenient if a filter could be added to exclude sets that are or aren't retired from a search. That way, you wouldn't need to go look on the set's page to see if it is or not. Whenever I look at my wanted list, I sometimes want to just look at sets that I can currently buy from amazon, [email protected]
, etc. I'm not sure if this belongs here or in the brickset.com section, so mods, feel free to take any necessary action.
