It would be great if users could contact an internal support "champion". Internal support could be reached via a chat window that's somewhat hidden unless required. It would be good if chat support supported an integration (Skype, SLack etc) so the support person can work in an existing system.
Thank you for your idea. One suggestion would be to include internal contact details in the Product overview section or in a note. This way users could find the champion and contact them directly.
Since these types of tools are generally available internally, we are unlikely to implement integrated internal chat. We hope you can understand.
