Cinemachine encourages experimentation because you don’t need to write any code to create a procedural / tracking / smart camera. No need to bother a programmer with a ‘hey what if?’ idea, just try it out right then and there. Hit a number of dead-ends to find the one magic idea. Your cameras no longer have to be a frustrating time sponge, turn them into something fun and amazing.
Since Cinemachine works in preview and play mode and all settings are saved regardless of what mode you’re in, the iteration loop time is zero. Tweak the settings and see results instantly. There’s no need to remember any numbers or settings since everything is saved all the time on every control.
