Windows Vista Side Bar

Just what the title says. I don't know if ne one else mentioned it but a vista side bar would be cool. The side bar could indicat how many files are being uploaded and downloaded or some sort of quick overview, maybe give you a quick tally of how many people uploaed from you in a given time period. You could also put an exit/exit after transfers button or something of the sort AND make it so that when you do hit exit after transfers it waits til all upoloads are complete (closes remaining open slots) and then shuts down. I find that a lot of the sidebars are useless but I think that this one could be useful.
