Great plugin! But would it be possible to add some multisite capabilities?
For example, it would be great, if the plugin was network activated, that global credentials could be added that would be used on ALL the sites on the network. So the sub domain admins would not need to worry about the settings (if fact it would be better if they could not even see the settings).
I know there is the complication with domain mapped sub sites, but this issue could be worked around.
