"WiFi Enabled" setting was moved from Advanced Settings to main settings.
The ability to set a controller IP or Host name was added to advanced settings so the app can connect without scanning via mDNS. This allows the use of multiple routers and/or repeaters on the LAN. It also allows the use of a VPN or Port Forwarding in your router (port 5438) to access the controller remotely either directly via an IP address or via DDNS. It is recommended to set a password when using Port Forwarding.
