Mobile 4.0 gives you the ability to view products in a "Split Pane" view on iPads only (instead of going to a full product details page). This setting will be enabled on the device-level, so all users sharing the same device and using different logins will have the same setting enabled/disabled.
To enable this setting, simply follow these steps:
(1) Log in, tap on "Menu" and scroll down to "Settings."
(2) Toggle on "Split Pane" and close the modal.
(3) View any product in a gallery, and the split pane will display from the right.
