At the urging of red satin doll, I've added a link feature over on the right below the search function. The links go to the Introduction and to each season. That way, you find all the episodes for a given season collected together (though in reverse order). I hope that makes navigating the site easier.
If anyone has other suggestions, feel free to make them. I haven't spent much time figuring out how to get blogger to do stuff, so I may be overlooking a lot.
