I suggest to add more option to configuration / Single file customization :
- change (or hide) the great down-arrow icon. Or change it a bit smaller version
An option to change download icon color- an option to hide size and format
- an option to hide preview text
- an option to substitute preview text with an eye icon
- an otion to show/hide the file description below the file name
Please extend role manager: who can insert WP File downoad shortcode into the post.
thanks and best regards
