Rearrange open applications in Taskbar ?

Gnome on Ubuntu has an extremely useful feature where I can grab an open applications button in my taskbar and move it. For instance if I have Opera/Filezilla/IE/FF open in that order, and want it organized so that the 3 browsers are next to eachother, I can grab the one for Filezilla and drag it all the way to the right and it will stay over there.

Does Vista have anything like this ?

I'm using Vista Home Basic and it doesn't seem like I can move open applications around as it is.
