No, that page is not at all helpful. What is so difficult about providing a comprehensive reference list that details all supported shortcodes and includes a complete description of all the options/parameters that each one supports? There should be one document that details all of that information in one location, not a collection of disjointed videos.
For example:
[short code 1] == summary of what it does
[parameter 1] == required/optional == syntax, description, acceptable values
[parameter 2] == required/optional == syntax, description, acceptable values
…
[parameter n] == required/optional == syntax, description, acceptable values
usage examples
[short code 2] == summary of what it does
[parameter 1] == required/optional == syntax, description, acceptable values
[parameter 2] == required/optional == syntax, description, acceptable values
…
[parameter n] == required/optional == syntax, description, acceptable values
usage examples
I’ll bet you could write that document in a fraction of the time it takes to make just one of those videos, and it would be infinitely more useful.
