After a long time the new Router Control v1.1 is available by now. It contains a lot of more features like monitoring of port forwardings, router hijacking detection and a new diagnostic tool.
Thanks to everyone who gave feedback directly or by uploading the router schema. I want to encourage everyone to enable the new automatic error reporting which anonymously reports bugs to the Schema DB. Please report any issues you encounter (e.g. bugs or missing texts or images).

UPDATE: Hotfix available: v1.1b! Thanks to KTMFactoryRider and the new automatic error reporting I was able to fix a lot of severe bugs during the last days and came up with some critical improvements.
