iOS: Pan knob and mixer thumb scaling bad

Can the Pan knob and mixer slider thumb be made larger (with respect to the window scale)? On an iPad Pro 12.9", the per-channel Pan knob is very difficult to click/hold accurately without an Apple Pencil (and dubious even when you do point at it with one). If you run your iPad with Display/Brightness > Zoom > More Space, the Pan knob is tiny and too small to easily manipulate, especially with a lot of participants; and my fat fingers can't move the mixer slider at all. **To Reproduce** Get on a 12.9" iPad Pro. Set Settings > Display/Brightness > Zoom > More Space. Open Jamulus and look. **Expected behavior** Bigger Pan knobs/volume sliders. Would also be useful to make the mixer sliders slightly wider so you get better checkbox labels besides "G, M, S". **Operating system** iOS 26.4.2, iPad Pro M1 12.9", iOS App Store **Version of Jamulus** 3.12.0 **Additional context**
