SyncThingy is a simple tray indicator for Syncthing written in C++.
Following the KISS principle, it allows you to see if Syncthing is running, stop it and manage it using the default webui.
A pleasant way to access and maintain Syncthing, without all the extra GUI re-implementation other projects have. ...If you get the Flatpak working (my tip: don't use the autostart option in the app, but instead just add it to startup applications)
