I was just coming down to report on that crossed-out thing as a QoL issue! It also struck me that once you've started building a unique building, you can't see its progress. It'd be nice if the build queue could be expanded to show you more information (that; what the things in the queue are; how long they'll take...especially since you can reorder them, as I just learned, it'd be nice to know what effect that would have).
