growl and notification suggestions
system_advanced_notifications.php has a button to test
growl, but no indication locally (in the GUI) if used or not. In
particular shouldn't it warn if the IP address and password is blank?
In addition, there is no indication locally (in the GUI) if the
Test SMTP Settings button did anything.
Since it says uses the currently stored configurations,
it should show what they are here just in case changed above,
or when the test is done it could display what settings were used.
or could use multiple submit buttons and call this one
Save and Test SMTP Settings?
