Hi Lely - thank you so much. This is good to know. I need to figure out how to integrate a 3rd party library inside a Cornerstone managed page. Do you have any resources that talk about that? I've hand coded WP templates before, but this whole CS mananged online editing is a little mysterious. For example, do people like me end up downloading a template and add the JS, libraries, and CSS in that and upload? Or, can we install somehow inside of Cornerstone? I see on that samples page that some of the approved components can be enabled as extensions. What about a completely random library like say d3.js?
