List of Plugins Usage

I'd like a list of all plugins across all sites

I can see the plugin list per site by going to each site, but I need a list of all the plugins so I can see which plugins are used on which sites. This will help me manage my licenses as well.

Ideally the list would be an expandable (tree) list of the sites using the plugin with a count of the total sites.

Also Note: Listing the plugins for the sites horizontally across the page is a horrible way to show them. I can't make my screen wide enough. At the minimum, enable horizontal scroll. Ideally, this too would be a tree.
