[Feature Request] Filter episodes by Missing episodes + Aired

[GnaXi]

Hi!

Love this plugin. It's a great way for me to keep track of what shows I'm missing episodes on.
However, it would be great if I could also narrow it down to episodes that have actually aired.
As you can already, when you go to a season of a show, see if the episodes missing are "Missing" or "Unaired", I guess it's just a matter of adding it as values in the filter.
