Add 1 year growth rate and 5 year growth rate to options for editing portfolios, as can be generated from the enlarged chart.
Also, go back to the 2-cycle log option for charting, which really gives a much better representation of a stock's price increase on a percentage basis.

It is really a "convenience", but a nice one, in this crazy market! I was surprised that I could not locate that option for my portfolios. (Did I miss it?)
Since the rate can already be generated, it seems like you should be able to easily transfer that function to the portfolio options page. What do you think?
