Thanks to everyone for the feedback (and bug reports) following the last UI update. Although not every aspect of the new design was well-received, the process was well worth it. Your feedback, and using the new layout, helped me to clarify the most important features and functions of the site.
I got inspired over the weekend, and started working up the next UI update. In some ways we are moving back, and in some ways we are moving forward.
At any rate, expect a fairly significant change in the next few days.
