It would be nice if we could just set functions in the step definitions, to be triggered before and/or after the step appears. Maybe something like this: ``` intro.addSteps([ {...

I think maybe you would need to configure different actions to take place if someone is hitting "Back" instead of "Next".

I get this error after trying to install the patch: `xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools), missing xcrun at: /Library/Developer/CommandLineTools/usr/bin/xcrun`
