I haven't looked at the developer documentation for Experience Builder in some time because it has just not been useful enough to try to read through. But I looked today and it is so much better. If you haven't looked at the documentation recently, I think you will be surprised how much it has improved.

Thank you to @Jianxia and the Experience Builder team doing this. Documentation isn't as flashy as adding new features, but those new features aren't useful if no one knows how to use them.
