I realize that the S2 switch (top left) can be flipped up and down repeatedly to enter RTH mode, but does the position of the switch actually do anything useful in flight? It seems like a complete waste that it can't be configured to select between different IOC modes (like was done on the P2V+). As far as I can tell, any time I want to switch to an IOC mode I have to take my eyes off the quadcopter to look at the tablet screen, and make a tap to select IOC mode and another tap to confirm that I really did mean to tap the first time. Why can't we just have a setting to pre-select 3 IOC modes for the 3 positions of the S2 switch? We already have to specifically enable Multiflight mode in the settings, it's not like you can accidentally put the bird in a screwy mode. Just seems like a step backwards given that the P2V+ had this sort of functionality.
