Panasonic Inverter Microwave

The old Samsung seemed to be on its way out (no light, and really noisy fan), so I bought a new Panasonic Inverter, thinking this is better tech - no more on and off boil over then do nothing kind of low power.

The inverter variable power is fine, but as far as the U.I. is concerned, I'm missing the old Samsung.

• No  one button, one minute on full power
• Can't change the power level while the thing is running, or even when it is stopped. To change power you need to cancel, set new power, set new time, then start again.
• Can't add time while its running. Eg. this looks like it needs another 30 seconds, add them. Again, need to cancel, set power level again if it is not 100%, then set new time, start.
• It has a 12 button keypad, but the buttons are labelled 1 to 12.  They can't be used to enter numbers for time or power.
• No way to turn off beeps for every button press.

I can't think of any excuse for this brain-dead lack of features.  I just assumed they would be available...
