on macs, the side bar stocks widget has so much potential. A simple but powerful improvement would be to implement real-time quotes. I would literally pay a premium just for that feature. Maybe give a trial period and then charge monthly. Next I think it should be easier to add/remove/move ticker symbols instead of having to hit info and then scroll all the way down through my long list to get to the plus symbol. Simple but very effective changes would lead to mass adoption. just my 2 cents.

one more thing that i just thought of. maybe make it possible to sync my yahoo finance account with the sidebar widget on mac. that way i dont have to add and remove tickers twice.
