1) Thank you. I passed the issue to our developers.
2) You missed to set borders https://gyazo.com/04e6a857c741024c05ba4ec5d07f4929
3) There is no way to set scroll there. So, you may enable off-canvas type for the cart to show more products.
4) By default content of the page use the container width. If you want to stretch section or section with the content use Elementor section settings https://gyazo.com/266c38945c47fc7019126bf7f926c661
5) Do you want to change the color of the buttons? Go to Theme Options > Styling > change the colors of the Light buttons.
6) If you want to use our Brands option you need actually create brands and add products to brands, there is no option to import attributes to brands. If you want to show the attribute on the shop grid you may try to implement this by additional customization. You can submit customization request here.
7) That effect was added using custom CSS. So, you just need to remove custom CSS related to the hover of the product card. But I see that you changed the demo.
