Hi,
The front side bar can be edited in the WordPress live customizer.
In the admin panel, click on Appearance >> Customiz’it.
Then select the “front page” section. Here you can set your home featured pages and text : when you select a page in the dropdown list, Customizr displays the featured image of the page. The default text is the excerpt of the selected page.
You can write your own text in the dedicated field of the front page settings (featured text…).
To disable the featured pages area : select “Hide” in the dropdown list.
Hope this will help,
Nicolas.
