Arduino Lint has suggestions for possible improvements to https://github.com/GyverLibs/UART_RF:

Linting library in UART_RF
INFO: No header file found matching library name (UART_RF.h). Best practices are for primary header filename to match   
      library name.

WARNING: The library.properties paragraph field repeats the sentence field. These are displayed together so redundancy  
         is not needed.
