Let me first say how happy we are with your framework. I’ve found the user experience, the developer experience, and overall performance of the viewer to be excellent. I don't want to have my company name listed. Using your editor is currently providing us a competitive advantage over our peers — I don't want to make it easy for them to figure out what we're doing!
I'm becoming a real fan, because it's really a fantastic library!
I just had to change your example's filename and published it. Everybody's pretty happy with it. The nice and smooth behavior has been highly appreciated.
