Pretty good program - nice and small on the screen. However, it's a bit of a pain to switch between stocks - would be nice to at the very minimum have a keyboard shortcut to switch between stocks.. Or even nicer would be an alternate view option which could show several stocks at once. I imagine that most people would be more interested in tracking *several* stocks rather than just one.

Also, this is probably overkill, but it might be nice to allow for alerts when a stock value goes above or below a certain threshold.
