Trying to find that perfect balance between aesthetics, minimalism, and functionality is tough, but I've gotten a lot of help from the work of roth, Ryas, p3lim, Hal, and others. I still have some clean-up work to do in terms of adjusting visual elements, but I'm really happy with where my UI is at the moment.
