FYI, I have started development on the 6-pack Aviation Instrument panel mode, and it's going smoothly. This is targeted now for v7.5 (target date not announced).
Additionally, we're also planning portrait mode for v7.5. But no promises yet. Portrait mode is next on my workplan, but we won't know the true difficulty of this task until we start work on it, and measure our rate of progress. I'll keep you updated as we find out more (maybe within 2 weeks).
