When i'm doing bigger Productions with vMix, i use a Fullscreen Multiview most of the time. For Audio, monitoring the Recording and editing inputs i have vMix opened on another screen. Of course, the preview and output are shown on both screen, even though i only really need them on the fullscreen multiviewer. I actually find this a little bit distracting and it would be nice to use this space to just show all the Inputs.
So my request would be to add the ability to hide the preview / output and the Transition buttons in between, so that you'd have the whole screen available for inputs.
