I made links a different color instead of the default white. The stock theme had white links with no underline. I tried adding the underline back but it looks bad.
I think I'm just about done tweaking the theme. Maybe the suggestions picture could be better.
I've also figured out how to get custom image banners in the thread list and post list. But we'd have to get new pictures for those because it stretches the image to the full length of the page as you can already see in this post.
