Admins can now independently edit the mobile style of any template you create with the Template Tool.
To edit the mobile styles for the overall template, select the Template tab, then select Mobile Styles.
You can also edit the mobile style for any specific section, or column block. Do this by hovering your mouse over the column, or section, and clicking Edit Column, or Edit Section respectively.
With this feature you are also able to hide entire sections or columns from the mobile version.
