Other customization options include making it run at start-up and stay put in the system tray or using proxy servers to connect to Internet. Spiffy can open any installed browser to open Gmail, when the notifications are clicked. Since it saves its settings in a small file, it can even be used on multiple computers or from a flash drive. The portable version of spiffy does not require any installation and is only a single executable program.
Spiffy 0.5.7 is about 275KB in size and is only supported in Windows XP/2003/Vista/7. It requires .NET Framework 2.0; so in case you don’t have .NET Framework installed, do install it before using Spiffy. Spiffy has localized versions (not for the portable version) in more than 20 languages and you can opt to download the installable version or the portable version depending your usage.
