your plugin is good but it would be much better if it had the following options:
1. For some reason, yahoo finance does not show any day change value for currencies (the last number in the stock ticker line). Try for example EURUSD=x, or USDJPY=x. So you end up having a lot of useless zeros in your website. The solution would be to either allow the developer to eliminate the change value or to have no display for the change value for currencies only.
2. It would be very useful if the name of each security could be changed. In many cases Yahoo assigns very long or ugly names.
