I was involved in both the lobbying and the development of the original website and have provided consulting services to CalSTRS (who operates the site) ever since. I've watched over the past 18 months as the people at CalSTRS worked to redesign and modernize the site, the new site launched this week and I think they've done a great job.
Just a few new features you will see is an expense ratio range (low - medium - high) and a disclosure of whether the product will pay a commission when sold (no data on what the commission would be at this point). Comparisons are now simpler and all the data for mutual fund and annuities are in real time, including performance information. There are also filters to help you exclude certain products and a design that should allow for simpler navigation.
I've linked to a brochure and flyer below and you can watch a few of the videos as well:
