Alphabetical ordered list of class names and directives in Docs

I have been reading the Docs for several days and I feel like I miss an index of all class names and directives. Is there any chance that it will be added to the docs?
As a reference, the index would be very helpful to beginners like me who stumble upon code that uses classes or directives that are not present on the actual examples in the Docs.
Thanks a lot!
