I have just upgraded from version 7.2.4 to version 8.3.5 of the Windows desktop app. With version 7, you could have the application minimize to the system tray in Windows. However, this functionality is not available in version 8.

Please add the following functionality:
The application can be minimized (in UNLOCKED mode) to the system tray instead of the application bar.

Also, version 7 had a nice pop-up window reminder that stated that the application was already running if I tried to open the app a second time.
