I'm ashamed to say I didn't touch it in a long time. In the meantime I had a hard drive failure and lost my entire pile of design notes for the project. Thankfully by some miracle I managed to get back source code for the full graphical revamp so it's not that hopeless. It's not too much of a step back, since most of the notes were brainstorming and at least the filenames are intact, but it will be an even bigger pain to get back into the project.
