I will personally like a feature that allow me to add a note for a stock, or a note to an stock alert, basically telling myself that what I want do next for this stock , or for this alert when triggered. e.g. When it hits this particular value, I want to buy/sell more or review what I am currently thinking that I shall do. Instead of just a value alert, but now I need to rethink what exactly I like to do when I hit this alert.
