Production environment: error page for fatal errors

[eluser]Unknown[/eluser]
Of course those needs fixing, but if there may occur a fatal error, for example, when a file is missing, it would be nice if there was something more than just a blank page, in general users do not know what to do with a blank screen.

So besides extending the core class there is no way this could be implemented? Well, it is way better than nothing. Thank you for your response.
