Description: I'm currently using KDE Connect on Ubuntu with the GNOME desktop environment. While my system is set to dark mode, KDE Connect's interface does not fully adopt a dark theme. It appears that KDE Connect relies on KDE Plasma's theming and does not integrate well with non-KDE environments. Steps to Reproduce: 1. Install KDE Connect on Ubuntu running GNOME. 2. Enable dark mode in the GNOME system settings. 3. Launch KDE Connect and observe that parts of the interface remain in a light theme. Expected Behavior: KDE Connect should either: - Integrate seamlessly with the system's dark mode settings, or - Provide an in-app option to manually enable a dark theme for users on non-KDE environments. Environment Details: - KDE Connect Version: 23.08.5 (installed via 'sudo apt install kdeconnect') - Ubuntu Version: Ubuntu 24.04.1 LTS - Desktop Environment: GNOME Enhancing dark mode support would greatly improve the user experience for those using KDE Connect on non-KDE desktops. Thank you for considering this feature request!
