Would be great to set conditional actions for triggers, so navigation (or any other function) would depending on certain conditions. This would be particularly helpful for onboarding flows, where we might already have certain info about the user based on where s/he came from and/or previous interactions. For example, if we already knew the user's email, wouldn't need to ask for it again.
Similarly, this would be super helpful for auth if there's an error message, rather than navigating to the next screen, it would refresh the current screen and display the error message.
