Yes, it's only possible to show which camera is in use as far as I know when choosing to switch to that camera explicitly, not when zooming. The next version of Open Camera will offer more options to choose specific cameras (so this will allow explicitly choosing telephoto camera on devices that support it - not sure if the Note 10+ will, but does work in newer Samsungs).

See https://sourceforge.net/p/opencamera/tickets/1019/ for this request.

There is a feature request for supporting JPEG XL in Android: https://issuetracker.google.com/issues/259900694

Please see Settings/On screen GUI/"Force maximum brightness". (I am considering changing the default behaviour - recent phones have much brighter displays than they used to.)

Re doing this when locked, the QR code scanning quick tile can be used from lock screen (and presumably doesn't use up any lock screen "slots" - note that seems to be a manufacture specific feature anyway, stock Android doesn't allow launching third party cameras from the lock screen anymore unfortunately).

Android 13 onwards supports QR code scanning direct from a quick tile (the tiles in the pull-down notification bar), as far as I can tell this doesn't rely on the stock camera app. If you want to do it direct from Open Camera, it seems Google's new "circle to search" functionality now supports QR codes (long press home button, the circle round the QR code - I tested this works on my Pixel 6 Pro).

Is there a stack trace for the crash? Does Open Camera crash even when not running from the debugger (or even from Android Studio at all)?
