This looks absolutely stunning. The range of components is impressive, and the UI is really quite intuitive (I got a simple circuit running with measurements in a minute or so).

Looking through the changelog, it seems that MCU simulation includes peripherals like I2C, PWM, and all sorts of low level stuff like power modes (sleeps, wake).

There are lots of situations that don't demand highly accurate simulation, especially for educators and hobbyists, and accessible software like this makes experimentation a joy.
