Feels like they didn’t play test it. The notification at the bottom for every adjustment of the Julia seed is a little silly for two reasons: first because you can’t really read it in the time it’s there and second because for fine adjustment of the Julia seed you stack up like 20 notifications that display one by one.Second issue: the drag to adjust position feature moves you double as far as you actually slide for some reason. This makes it difficult to control while also zooming in sometimes.Third issue: where you press on the screen doesn’t at all match the Julia set displayed. I click on a mandelbulb, I receive a Julia set corresponding to as if I pressed on the central cardioid. I press outside the Mandelbrot, I still sometimes receive a Julia set that’s filled in with black.If you come through here and fix things, make the motion smoother and not flash when you make a change in position. The flashing was troubling. Then you should add a feature in settings that allows the Julia set to continuously be set to the center-of-screen position on the Mandelbrot set. Wouldn’t hurt to add a little negative color dot at the center-of-screen of the Mandelbrot so you can see where your Julia set is coming from.
