Options
Who can mint?
This is a smart contract setup. If anyone can mint it means that anyone can create a NFT item on your Marketplace. Otherwise, only the contract owner can mint new NFT items.
What user roles can create NFT items on your Marketplace?
This is a WordPress level configuration. Choose the WP user roles authorized to create NFT elements, both in the Backend and the Frontend of your site.
All users can edit all NFTs
This is a frontend setting to allow all creators to modify the data for all items. By default, NFT items can be modified by their authors, but if you want all authors to be able to modify all NFT elements, activate this option. (Not recommended)
Show OpenSea link
If your contract is deployed to Ethereum mainnet or Polygon mainnet, an auto-generated link to OpenSea will be displayed in the item view
Use pixelated images
By default, each browser will render images using aliasing to a scaled image in order to prevent distortion. Check this if you want the image to preserve its original pixelated form. This is usefull if your items are icon-like images
Examples of pixelated and atialiased images
Enable Sub-Collections?

Your galleries will be show on the top as a dropdown list
