This tray icon only closes when the 'Quit' button is pressed. \n \n How to configure your cloud storage service:\n 1- When you launch this application for the first time you are shown the 'Manage' menu, that allows you to try to automaticaly configure your Google Drive Account. \n If you click the 'Google Drive' Button, your internet browser opens on your cloud account service. You have to log on and autorise 'rclone' access to your account. After the config process is done, if you don't want to configure more services, click the 'Quit' button and the main Window pops up. From there you can double left click your Cloud account name, to access it's contents. \n At any time, in the main window, if you click the 'Manage drives' button, will will be presented with the initial configuration menu. \n 2- Manually configuring cloud storage services: \n if you click the 'Manage' button, a terminal will pop open. You have to use the keyboard to perform your selections. After you finished seting up your cloud service, press 'q' from the main terminal menu to exit. Restart this application to access the 'remote' drives you just configured. \n \n SECURITY WARNING: \n Do not use this application on a shared computer, because this provides access to your cloud accounts without any need of entering a password!!!" --button="On line help":'desktop-defaults-run -b rclone.org/drive/' --button="Close":1
