Hi @GhostFire90 I´ve implemented this in https://github.com/RoStCode/microshell/tree/issue6_cmd_history and it is working good in a "production environment". However, I would say that code is not yet ready for prime time. Some unit tests are missing and code could be improved. Feel free to try it out and suggest improvements.
