Add "show all controls" button, that allows most of the "set once" controls to be hidden on small screens. Please feel free to make a better icon! Could also be hidden if !ANDROID, if you don't like it. Add pinch and pan gestures, for frequency scrolling and zooming in to spectrum. Queue frequencies requested by scrolling, so intermediate frequencies can be omitted, if device is slow to update its frequency. Support non-integer pixel ratios. Add popup sliders for dials. Add DialogPositioner for dialogs. Add layout to spectrum markers dialog, so that it can be resized, to fit on smaller screens.
