List only plugins that are exclusive for Networks
Did you ever wonder which plugins are Network only?
If you're not familiar, this kind of plugin only appears in the screen
available in Multisite installs. And there's nothing there telling us that.
Well, not anymore, this plugin does that.
A custom screen will show only those plugins. And when viewing other plugin's screens, they'll be marked with a small customizable icon.
Uses Font Awesome for displaying icons.
