I’m considering replacing const __FlashStringHelper in Tiny4kOLED_common.h and Tiny4kOLED.cpp with DATACUTE_F_MACRO_T defined in Tiny4kOLED_common.h as

#ifndef DATACUTE_F_MACRO_T
#ifdef AVR_DIGISPARK
#define DATACUTE_F_MACRO_T fstr_t
#else
#define DATACUTE_F_MACRO_T const __FlashStringHelper
#endif
#endif
