this customize( array $optionArray)

Sets any configuration option, with no checks for type / validity

This is more or less a bandaid to remove the handcuffs from users who want to add options that Google has added, that I have not. I didn't intend to restrict the user to only select options, as the goal was to type check and validate. This method can be used to set any option, just pass in arrays with key value pairs for any setting.

If the setting is an object, per the google docs, then use multi-dimensional arrays and they will be converted upon rendering.

This method will most likely be brought into 3.0 to prevent BC breaks, but I will incorporate the same functionality without the need for the extra customize() method call.

Parameters

array $optionArray

Return Value
