Three layers of study notes

Floyd Johnson

The ads for the FSB say:

     Three layers of study notes

I am unsure what this is referring to.  I can see only a layer that has basic notes like any other study Bible, what (and where) are the other two layers.

Some of those will have a plus sign for more in-depth treatment, this is layer 2.

The links to e.g Lexham Dictionary for even deeper information are layer 3.

At least that's what I understand.
