Check out the Zoom video on the "What's New in the Agile Platform 5.0" thread. Your wish has been granted!
I'm quite amazed with that feature!
But I also felt a mix of odd shivers and vertigo... I sure hope I won't need to dig into that big of an action flow which you demonstrated in the video :)
I also hope fellow developers won't be too motivated to build a 30+ node flow now that we have the zoom feature :)
...other than that, excellent work!
