1) We don’t have custom labels in our theme. Look for additional plugin to implement that.
2) There are no such options in our theme by default. It’s possible to implement by additional customisation only. You may submit customisation request here https://wpkraken.io/?ref=8theme
3) There is no such option in our theme that allows users to upload custom files. Either look for additional plugin or submit customisation request.
4) WooCommerce does not allow to remove categories slug from the permalinks at all. All the available WooCommerce permalink settings you can find in Settings > Permalinks.
5) We would recommend you to install some SEO plugin (Yoast SEO, All in one SEO or any other you like). It helps you to adjust SEO settings.
