Is your feature request related to a problem? Please describe.
If a part of the CMS is not working for any reason you sometimes get an error message. These error messages can be rather intimidating to the not so tech savvy user.

Describe the solution you'd like
Humanize the error messages / alerts / notifications. Something like 'An error has occurred. Try again or contact your friendly developer :) To check what went wrong click here / open console'.

Describe alternatives you've considered
Show error messages based on user roles could be a nice feature. If we know you're a developer we can show the error immediately. If we know you're an editor we should try to be less intimidating.
