Thanks Jeff. I'm actually Ruaridh's SoN mentor, and we've been discussing visualization ideas. His project is a nice complement to Cerebro 2, since it offers visualizations of features over time. He was mentioning maybe even making one of the visualization functions in his project actually open up Cerebro 2 for a detailed look.
I'm excited to see all these visualization ideas becoming a reality! It will be very useful for working with the CLA.
