Thanks for the feedback, I understand your need, and you have fixed it already to suit you.
Anyways, I think that in regular cases, the "admin" user should be limited by panel context, as the panel context is thought to be used in multi tenant setups, and the admin granting access to other contexts is indeed a bug/problem.
Be sure you backup your recordings.php file so it does not get overwritten if you upgrade fop2 in the future!
Best regards,
