            A dictionary which contians information on the API. At least containing the `api_thread` key with the

+           The `matrx_paused` key can be used to start MATRX paused (default behaviour) or unpaused when using a

            be stored (minimum of 1, the current state). Note; too big of a number increases RAM usage!
