Remote Control - Quick enable/disable per-device
It would be really helpful for the proclaim desktop app operator to be able to control which external devices can control at various points of the service.
This would be the same functionality that I use in EasyWorship at one of the other churches I am involved in. There's a list of devices currently connected/approved, and I can just click to enable that device to control at a point that's appropriate in the service.
Most of the service is usually run by the computer operator, but it's useful to allow say just the preacher to control when they are up there, and disable it when the bible reader is there so they don't accidentally advance the slide
