How to reduce left padding on mobile when readable line length is on?

Hi Christophx, is this relevant? You can keep separate settings per device.

Separate Settings for multiple mobile devices

Mobile app (iOS) has settings that sync across devices - iPad, iPhone, etc. The settings should somehow respect the preferences per device. A notable example is the pinned menu feature - it’s perfect for my use on iPad Pro but on iPhone it takes over the screen.
