@exposure, if @Moors7 hasn’t discouraged you from making your own, these libraries have been ported:
PID including auto-tune (available on the IDE)
Adafruit_MCP23017 (available on the IDE)
Adafruit_RGBLCDShield (I am currently porting it)
EEPROM (in Spark built-in function or with the flashee-eeprom library available on the IDE)
