Squeak TaskBar is a simple clone of the taskbar found in Windows 95. In is composed of three parts- a "Start" button, which opens up the "open..." menu; a list of open windows, in the order they sit on your desktop; and at the far right, a digital clock that shows the date when you click it. This package was originally produced as a demo to a newbie on #squeak on irc.freenode.net, written in a half an hour. As such, it isn't perfect, but it appears to be pretty stable for what it is. There are some features which would be nice, like auto resizing when the world is resized, etc. I have added some already, but not integrated into this package; if you are interested in a more functional taskbar with these features let the author know and he may make such features available.
