It's absolutely one of the most amazing places I've ever been. Words and images don't really compare to actually being there. I highly suggest it if you ever get the chance to visit.

And to answer your question. I have. And I made a mistake, there's actually two new watersfalls, I've been to both of them. I'll include a link, the two new ones are "New Navajo Falls" and "Fifty Foot Waterfall"

Both of them are amazing, however.. I would like to perhaps venture back up to this spot and see what it looks like now that it is dry. I'd also like to go all the way down even further to Beaver Falls which I haven't been to yet.. Though that ones like another 10 miles or something like that, so.. Definitely a lot of hiking!
