MQTT Client app - Beta testing

Why would you want to disable mapping?

not all mapping, just certain ones for debugging or other purposes. Like you can disable individual event scripts.

We will think about the throttle.

Throttle is just one of the possible filter functions. But to be honest, i've checked my current mappings and this is the only stateful function that i'm using, so maybe build-in implementation will be sufficient. Still some kind of global functions might be useful in the future.
