Visual indication for Lister having admin privileges?

I'm wondering whether it is possible to get some feedback about the current mode (user or admin) the current Lister is using. For instance I would really appreciate to have a red background for the file display border (or the status bar or whatever else makes sense) if the current lister has administrator privileges. That would prevent me to make some changes by accident or to keep in mind that all forked processes will become privileged also.

The window title and the admin mode button appearing pushed in are the only possible visual indications right now
