Interactive text tool, please test

Here’s an interface for browsing and searching Shakespeare’s plays. I wanted to design a graphical index for visualizing the plays and getting an overview of search results.

I’m trying to keep the design simple, with a focus on the content. Still, I’d appreciate some ideas on how to spice things up a bit. The search function is a bit of a kludge, if you want to hammer on it a bit, I’ll be grateful for any bugs you can turn up.

Thanks, testers!
