I have an idea, but it would likely take quite a while to accomplish. Combine Pokearth, the Animedex, and the Episode description section together. Basically we get an Anime Pokearth. Here's how I picture it:
When you first click the link you get a map like the normal Pokearth. It has several highlited locations all over it, not just in the main locations from the games. When you click on a spot it gives you a page listing every episode of the Pokemon Anime that took place in that area, along with links to the episode descriptions and pictures. In the ones where they didn't actually announce their location in the Anime itself, you can just click on the route between the last place they had visited that was also found in the game and the one they were going to visit next.
