A DCS-BIOS-based plugin for Touch Portal (Macro deck remote control for PC) where you can use Android or iOS phone/tablet as secondary display to focus on parameters such as extension of flaps and speed brakes, wheels fully or partially down, remaining chaff/flares, states of non-frontal control switches, digital readings for warbirds (eg. altitude and speed), and etc.
With DCS-COINS version 2 onwards, you can issue DCS-BIOS commands to DCS via Touch Portal. However, hold action is not supported at this point in time.
