Please use B&W text in documentation

In some newer STM32 documents, such as ES0418, text is rendered in various tints of blue. This results in decreased readability and problems when printing.Can ST please constrain fancy color schemes to marketing material, and use conservative black-o...

Resolved! Advice, please, how to view the function call tree and the contents of the MCU stack using STM32Cubeide. After the program crashes in debug the program loops in Hard_Fault_Handler () and it is not clear what cause such event.

What ability to view the contents of the call stack in CubeIDE is present?, i.e. what functions were called before the crash, preferably in the form of a tree
