It needs a few things that I liked about GF:

1) If I click a different period in a chart, it should show me the different in price over that period as a %. I want to be able to see the chart for the last 6 months and be told what % the price changed.

2) It needs options chains.

Some small tweaks would also be nice:

1) The news line length is basically unreadable. 2) Font size is too small. Really hard to read the site.

But overall I like it.
