Ah yes, I remember playing with your build and seeing those changes, it was a cool idea actually - imho a better use of the two finger gestures than the current defaults (panning around the map). So perhaps the best solution is to add an “Immersive mode: true/false” setting to the Android settings. It defaults to “false” (preserving current behaviour), with a description along the lines of “Hide the navigation bar. Use two finger swipe up/down to toggle quick shortcuts and virtual keyboard.” When this setting is enabled, the “Two finger swipe up” and “Two finger swipe down” action mapping options are disabled to indicate they cannot be used in immersive mode. Sound okay?
