CP checker misleading warning on customized toolbox
If you create your own toolbox then the checker warns you that its namespace is unknown. It won't stop CP to work propely but is fairly misleading for users who would not understand why they get such a message.
The problem lies in the _known_ns method because the known_config_namespaces does not contain the customized namespaces.
I'm not how difficult it would be to pass those new namespaces to the checker.
