Installation
- Unzip and run the setup program.
- Launch the application and right click the icon to select Preferences.
- Enter your Google username and password and click OK.
- You can wait until it starts displaying, or just click the Check Now to test it out.
Notes
- Proxy support is partially supported. If you have a manual proxy configured in IE, it will pick up on that. It won’t handle autodetected proxies though.
- The “Only display items with label” field takes space separated values. You can put in as many as you’d like. This is very useful when you only want to be notified about particular feeds that you’ve placed into a folder.
