Hello,
1. In order to edit the header banner, go to Products -> Categories -> edit some category -> then upload the image in the “Image for category heading” field.

To make the page title bigger, enter the page option -> below find the “PAGE TITLE OPTIONS” section, and there enable the ”Large” button in the “Page title size” option.

2. To show only categories on the shop page you need to customize the shop page by clicking on the “Customize” button above the header -> next go to WooCommerce -> Product Catalog -> in the “Shop page display” field select the “Show categories” option.

You can show different categories on your “Product” page using the “Product categories” element in the page builder.

3. To change the “Browse category” text try to use the “Loco Translate” plugin.
Here is a video on how to change the text using the Loco Translate plugin:

Unfortunately, our HTML structure of the “Browse Category” menu doesn’t support opening the menu by click.
