This commit makes the plugin adhere to the new plugins arg-passing scheme by expecting full-form boolean args instead of short-form booleans. This necessitates that we introduce a new argument, here "track", to accept "r", "w", or "rw". Also, it makes arguments not positional and we only care about the last value specified for a certain argument. callback/inline args are now supplied separately as bool arguments so that both can be enabled individually.
