Ah, got your point. Thanks for correcting me. I misunderstood "gpii.primarySchema.magnifierEnabled" as a more/less status while it actually tells whether magnifier is turned on or off.

Yes, I agree that digesting more/less toggle internally by adding grade to a panel component is better than adding confusing primary schema objects. 

"expandingAdjusters" is currently added as a grade to "gpii.panel.increaseSizePMT", it would be nicer if it can be associated with magnifier subsection only, in other words, to directly connect it with "gpii.primarySchema.magnifierEnabled". This will make the expanding semantically sensible and also accommodate the case that more than one sections in for-example "increase size" panel have more/less feature.
