I've a site set up with your awesome Pro Sites plugin in order for clients to sign up and create their own sites. I'm also developing my own "dashboard" plugin for those clients to customize their sites. What I'd like to achieve is to be able to retrieve and display the individual client's Pro Sites subscription (and other related) info, and also allow them to upgrade or downgrade within the same interface without leaving their own site.
Question: is this possible and if yes, how? I'd like to have a more streamlined experience within the same interface instead of hopping in and out of sites as it does so currently.
Any help, tips, and other pointers are welcome.
