Pop3eye is a POP3 email notifier. It can be placed in a "dock", or use a regular or undecorated popup window. Regular expressions are used to filter email. It can display up to 20 partial lines of the email body in a tooltip window. It can monitor and display an unlimited number of accounts. You can choose to show messages using regular expressions, or delete messages from the server.
The goal of the General Applet Interface Library is to give programmers a simple yet powerful applet interface. This library supports wmapplet/dockapps, GNOME 2 panel applets, and ROX panel applets. The applet programmer doesn't have to care about where the applet will be used, since the library handles that. Over 50% of the code in a dockapp and a GNOME 2 Panel applet does only one thing, setting up the applet window. With GAI, this can be reduced to just a few lines of code.
