Layout Editor is a tool of the Theme Tweaker add-on that enables you to edit a page layout. Using this tool, you can drag‑n‑drop the info blocks to change their position. It can also help you to change the store logo, favicon, and Apple icon, if necessary.
To start using the tool, open the storefront while logged in as an administrator. You should see the Theme Tweaker panel at the bottom. Locate the Layout Editor tab and click on it.
You will see the tool panel divided into three blocks:
Logo & Favicon
[N] disabled blocks
By using the sections Storefront layout and [N] disabled blocks, you can adjust the layout elements on the page that is currently open; the section Logo & Favicon can be used to make changes storewide.
