[Andy Dadekian]"It seems to be a deal breaker for many people."
There's no broken deal so I'm not sure what you mean by this.
You can export them as separate audio files as needed.
It doesn't display in single "horizontal lines" like tracks but functionally Roles works for breakdown. Granted it could use a few more features for display and acting upon them as a group but I wouldn't call it deal breaker.
BTW there's always warranted critique but I have a personal pet peeve when people uses terms like "deal breaker" and don't articulate what's the issue. I personally assume when people use language like that, they don't know the app well enough to articulate an issue so they parrot a near meaningless pejorative. Roles have existed since 10.0.1 if memory serves me.
