Can you describe how WP Media Folder works in WordPress Multisite?
Can all the settings be hidden from sub-site admins
can individual sub-site media files be cleared from the server and only served from an Amazon S3 bucket
does the superadmin have total control of media files on the network, can you give individual sites control over all media handling.
The reason I ask is because plugins vary in how they work in Multisite. Some let you hide menus from the subsite admins, others allow everything by default and the superadmin has no control. Some you network activate and it's the same for all subsites, others let you give different sites different tools and settings. Some put the superadmin controls in the network admin area where they belong, others put them on the main site so the subsites just inherit those settings.
One example, a competing plugin to yours as I'm sure you're aware, is WP Offload Media. It can be Network Activated and then the superadmin has a special page under the Settings menu in the Network Admin area, which is how it should be done.
What controls does the superadmin have over the network and where are they in the control panel, and how granular is that control i.e. can you give individual subsites access to functionality or is it the same for all sites.
