I have great respect for people pursuing their special interests with such perseverance - you clearly care about zooming UIs.

And so do I (just to a lesser extent)! It’s a great way to express hierarchy.

One thing I encountered is that it becomes all buggy after using the slide-back navigation gesture in iOS Safari. Yet this being natively handles would be a really cool thing to me, like those iOS “close back to thumbnail” gestures you sometimes see when scrolling up/down that I haven’t really seen replicated anywhere else.

That means a lot, thanks. The iOS back gesture thing is tricky but would be really sweet to pull off.
