Today I was googling to figure out how I could minimize any application to the Ubuntu system tray.
I am very used to Outlook and I have recently migrated to Thunderbird, so I was looking for a method to minimize Thunderbird to the system tray.
I found two solutions.
The first one was New Mail Icon, which is an extension for Thunderbird. It works like a charm, putting the Thunderbird icon in the system tray. This icon changes when a new mail is received.
I also found the AllTray application. With this software you can minimaze any application you want to the Ubuntu system tray. Pretty cute!
To install it, open a terminal and type:
sudo apt-get install alltray
