Hi,
The logic level signals don´t carry much current. Thus they are less critical. Additionally the driver IC has some schmitt trigger inputs. The hysteresis helps to ensure proper function.
But GND is the reference of the signal. Thus you still have to take care about GND wiring.

Mosfet Source should have a GND plane for the bulk capacitor and the fast capacitor to the high side_drain.

This reduces stray inductance.My question is what is the reason behind using twisted pair?
"* I miss a fast capacitor from GND to high side Mosfet drain, short wiring."
Yes, therefore I miss it.I did not quite get it, high side's mosfet drain is not connected to ground nor to fast cap. How do you mean?
