Well, working functions is a start! reading this thread I noticed the GLCD support in m2tklib.
Please note that I was informed about a bug in M2tklib for GLCD recently. I have released a new version of M2tklib for GLCD today.

I'm using LiquidCrystal with a shift register attached LCD. I've hit my first problem though and I suspect it is because of the shift register:
error: cannot convert 'LiquidCrystal_SR*' to 'LiquidCrystal*' for argument '1' to 'void m2_SetLiquidCrystal(LiquidCrystal*, uint8_t, uint8_t)'
Don't read too much into the code, top bit only really needed as I've edited the menubackend code I had.
Question. I have 3 buttons up, down & select , which you have no handler for, I thought no problem I can use SetKey() in my ISR? this is ok I assume?
