Thinking of prototyping specifically. Just to be clear - I’m looking for something that does what you intend to achieve, rather than not doing what you intend to achieve. For example, if I put one animation inside another, I’m looking for one animation to be inside another, as oppposed to one animation NOT being inside another. Sort of like the prototyping equivalent of a caclulator that divides when you select the divide button, or a car that turns on when you press the on button. Does that make sense? So, something that works as opposed to being a soggy baguette.
