I wonder if you could add your own made plugins (or others) that need to be network activated to work on Pro Sites.
For example: Restrict access to /wp-admin/myplugin.php for anyone lower than level 2 Pro Sites.
It shouldn't be that hard, the question is really: What piece of code needs to be placed where? Both in the self-made plugin and the Pro Site's core code, or only in the Pro-Sites code?
I would like this to be lightened up. Thanks :slight_smile:
