This is just a suggestion for the episode pages, but on Anime Vice we started adding a table header with links to each episode within an arc/season. It makes it really fast and easy to browse through an entire series. It's especially helpful for going through larger series.
Here's a picture example from ONE PIECE Ep. 613.
You can see the name of the arc at the top "Punk Hazard". That's the most recent arc. The arrows to the left and right are used to scroll through the various arcs. By hitting that arrow to the left of the arc name, I can quickly go to the first episode of the arc that happened before this one. With the linked numbers below, I can very quickly get to any episode that appears within the Punk Hazard arc.
Something such as this might be helpful in this new series format. Though, that would probably go with seasons instead of arc names for most series.
I was unsure about this when we first started adding it, but I've really found it helpful.
