Shell replacement questions.

I'd like to get the same windows that the task bar does for a shell replacement I'm gonna code. Also uhm. The code for the right-click content menus that the taskbar does. One more thing, the systray, again any code useful for it give it up! The shell will be released under the GPL.(if any of you have seen cylinderific, it'll be an add-on to this, along with desktop icons(I can do that)).

I'm thinking of shadowing the icons like XP. If anyone has some FAST code capable of this I'd appreciate it. I say fast because i can do it, but if someone has any optimized code for it that would be best.

Thanks,
