iOS: Pan knob and mixer thumb scaling bad

[mjknowle]

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

If you change the layout to fancy - does this get better?

Moreover, you only need to tap the pan dial and you can move it anywhere on the screen as long as you don't lift your finger.

Switching to Fancy (or Standard) does make things a lot better. And yeah, I'm aware of tap-and-hold on the pan knob, but on Compact, actually getting an accurate tap on it without an Apple Pencil was a frustrating game of hit and miss.

Defaulting to Compact is probably the right move on a phone, but it's worth considering defaulting to Standard/Fancy on iPads where you have the real estate.

Could you please take some screenshots?

I believe it should be quite easy to default to fancy on iPad but not iPhone. I must admit that I can only test on iPhone as I don't own an iPad (and don't plan to get one either)
