a nice feature would be the ability to specify a duty cycle for voltage/current signal sources in their control dialog and being able to have it as a parameter in simulations. (like doing a DC sweep and telling it to sweep V1.DUTY_CYCLE from 0-100% or 0 to 1).

@crumple, FYI:

Although not as versatile in other ways, you can adjust the duty cycle of the Digital Clock source:

CLK1.DutyCycle

Being able to specify and sweep an initial delay would be good too.

have just found this: PWM Generator in bottom Unsorted Elements. can do voltage controlled PWM output. did not see this before. it outputs fixed voltage only though, like the clock generator module, but it should be good enough for now.

Using a behavioural source you can make a fully adjustable PWM source:
