Lookup provider per TLD
Setting the lookup provider per TLD would be great. So having a default lookup provider for all TLD's except when a specific lookup provider for a certain TLD is configured. That way you could use the fastest option available for a certain TLD. For .NL I would request it at SIDN (using EPP once this is possible) and they don't have information for .DE or .COM. So having an option per TLD would be nice. We create our own registrar modules, having this option would be great for us.
