Series Tracking

I’d love if MDb added bonafide series tracking tools so I didn’t have to rely on supplemental apps. On the series selector interface, at minimum, it would be helpful if the series numbers could at least become highlighted in the same my-star-rating indigo color once I had tasted all episodes in a series. That would help locate the series where I left off. Presently, it takes a lot of scrolling around to see what episode I’m on.
