Syncthing Tray complements the normal web-based UI of Syncthing itself providing the following features:

• A tray icon showing the overall status of Syncthing
• A tray menu showing more detailed status information that also allows to quickly perform common actions such as triggering a rescan
• Notifications for certain events
• Quick access to the normal web-based UI of Syncthing
• Integration with systemd and launcher for Syncthing

Note that this is the desktop environment independent version. The Plasmoid/KDE-integrations might be installed via a different distribution-specific package (but cannot be provided as Flatpak for technical reasons).
