Changing line 314-316 of rtlsdr-handler.cpp seems to fix the direct sampling issue for HF:
vfoFrequency = f;
if (f <= 28800000) {
rtlsdr_set_direct_sampling (device, 2);
} else {
rtlsdr_set_direct_sampling (device, 0);
}
(void)rtlsdr_set_center_freq (device, f);

Cheers. Let me know if you need some help with anything. You're doing a lot of good stuff here.
Some other ideas:
Might also be advantageous to save the direct sampling setting as a parameter somewhere in the rtlsdr interface, initialised at -1. This way rtlsdr_set_direct_sampling() only needs to actually call the radio function from the dll/dylib if it is different from what it was. I'm not really sure what repeated calls does to radio performance (or if that's actually an issue with the rtl-sdr).
Was also thinking of trying my hand at writing an AirSpy HF+ interface for you.
