The Storefront Hooks Customizer gives you the ability to add content to Storefront’s template hooks through the WordPress Customizer.
This plugin only works with Storefront and Storefront Child Themes
You will be able to add content into the Header, Content, Homepage Template, and Footer sections of the Storefront theme.
Each hook is saved on a per-theme basis, so when you switch themes the options will be blank. If you switch back, you will see the options added back.

A simple plugin that turns the default handheld navigation into an off-screen sidebar menu with a “hamburger” toggle.
This plugin requires the Storefront theme to be installed.

I bought homestore theme recently and installed this plugin but it failed miserably so I deleted this plugin. Too bad Woocommerce doesn't provide technical assistance for this plugin.
