After using this for a few hours I have another suggestion … another suggestion … another suggestion … sorry, the flashing got to me! 
Those flashing cursor positions get to be quite irritating. Why not just use the black background for the selected item (without the flash). This way the color is still present on the text for that channel and the absence of background draws your eyes to the correct cursor position without the flashing. I understand that the color background makes the text easier to read, but that incessant flashing may lead to a seizure … a seizure … a seizure.
Now if we can just get BenF’s capture buffer fixes and the ability to save the capture buffer, then the Quad would be usable although not as user friendly as the BenF firmware has become.
