“Horizontal” and “Vertical” views seem like odd ways to say “Form” and “List.” And those terms are inconsistent with the way you name those views when you’re in the “Customize Form Fields” screen.
There, the red button says “Show in Form Only,” and the green button says “Display in List View.”
Friendly suggestion—change “Horizontal” button on the Contacts menu bar to “Form View,” and change the “Vertical” button to “List View”
And if you do that, I realize that “Show Form” and “Hide Form” now have overlapping meanings and might become confusing.
I’ve got a suggestion there too—change the “Show Form” button to “Enter Data,” and change the “Hide Form” button to “Display Data”
