I was wondering (and couple of users suggested it as well) - do we need to track separately movie quality for 720p, 1080p and 4k? Do you want to be able to filter your movies (and setup notifications) for when the movie is out in, for example, 4k specifically?
For now - it's one state - either HD released or not (though you can mouse over the HD released icon and see in which quality is it released), but I can add additional filters and notifications if there is enough demand for it.
HD releases is a Premium members feature only. If you're not yet Premium - seriously - it's about time you experience the site in all its awesomeness! It's free to try, cheap after and supports Next Episode greatly.
