A couple of layout adjustments and general bug fixes. Watch list: - **New Feature:** Added an experimental 'Large Photo List' option. When enabled, each watch in your list is represented by a larger version of your watch photo. Find the new toggle in the settings view to try it out. Feedback welcome. Split view and foldables: - Fixed a visual transition issue in split view where the accuracy graph would awkwardly swipe in or carry over visual state when changing watch selections. - Fixed a crash that could occur on iPhone Duo split-screen when selecting a watch under certain conditions with service log entries. Settings: - Fixed an issue where the app's display mode (light/dark) would default back to Light on launch, ignoring your saved appearance preferences. - Renamed the 'Lock to Portrait' setting to 'Portrait Orientation Lock' to better align with standard iOS Control Center terminology.
