Separately Load Related Lists with Fewer Clicks

Back in Winter ’16, we added a user interface setting to separately load related lists of external objects. To spare you from extra clicks, we’ve added common-sense dependencies between that setting and the one for separately loading related lists of standard and custom objects. This feature is available in both Lightning Experience and Salesforce Classic.
We added these dependencies.
If you do this... We do this...
Select Enable Separate Loading of Related Lists Select Enable Separate Loading of Related Lists of External Objects
Deselect Enable Separate Loading of Related Lists of External Objects Deselect Enable Separate Loading of Related Lists

To visually indicate the dependencies, we indented the setting that applies to external objects.
