 - On Windows and Linux, an event loop must be running on the thread, on Windows, a win32 event loop and on Linux, a gtk event loop. It doesn't need to be the main thread but you have to create the tray icon on the same thread as the event loop.
 - On macOS, an event loop must be running on the main thread so you also need to create the tray icon on the main thread.
 
+### Cargo Features
