The description of the portfolio in the portfolio tab cannot be edited when it is created from "trading systems" in the viewers tab. After creating the description there, and then transferring it to a portfolio, one cannot then edit the description later. However, if the same trading system is created from the "new portfolio" in the portfolio tab and choosing the same system by choosing "an existing trading system", then the description can be edited. It seems that editing should be available regardless of which way the system is placed into the portfolio because the description should be able to be fine tuned as circumstances in the future change-- for example I will sometimes write which account the system is traded in my brokerage or which brokerage I'm using for that portfolio and that can change in the future and I'd like to be able to edit it.
