 - `i`: Enable interactive mode. If set, any api commands passed on the command line will be ignored.
 - `k`: The kind of Voicemeeter (basic, banana or potato). Use this to launch the GUI.
 - `D`: Set log level 0=TRACE, 1=DEBUG, 2=INFO, 3=WARN, 4=ERROR, 5=FATAL
+- `v`: Enable extra console output (toggle, set messages)
+- `p`: Load a user configuration (given the file name or a full path)
+- `m`: Launch the MacroButtons application
+- `s`: Launch the StreamerView application
