Functional requirements

We are targeting to develop an Ext JS extension that can be used to show messages. This extension can be used within a container as a docked item to show messages. The message bar will be closed automatically when the configured timer is completed. This message bar will also provide a close button and on clicking on this button the message bar will be closed. The opening and closing of the message bar will be in a smooth animated form. This message bar can also accept configuration at runtime to show several types of state that it can change its look to, and can show a proper icon.
