Network Admin › Plugins: each plugin shows whether it is network active, on which sites it is active, or that no site uses it.
In a WordPress Multisite network, the Network Admin plugin list only tells you whether a plugin is network active. To know which sites use a plugin activated per site, you have to open every site.
VEO Multisite Plugin Manager adds that information to each row of Network Admin › Plugins:
It only reads data: it never activates, deactivates or changes plugins, and it adds no settings, tables or options.
The list is shown only in the Network Admin and only to users who can manage network plugins (Super Admins). Site administrators never see which other sites exist in the network.
