Please add more option to single file configuration

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
Tibor
