So on this page about halfway down it states: 
Create Custom Metadata Type Records
For SFA Field, enter Minimum Support Level.

I only see the Support Level field that was created on the account.  Also, I don't see that this is actually limiting the chosen fields (seems like that was the point of all of the new metadata fields).  Is there something I am doing wrong here, or is the example off?

Also, if anyone has built out a rules engine while referencing metadata, I'd love to see a link to an example of that.

Is there a way to input a standard sales force quick action (specifically email) inside of a custom component?
