Portfolio Only needs to be better

For me Portfolio Management is more than buy/sell transactions plus dividends and I think there is significant scope for improvement. If I see one of my stocks rise or fall significantly I want to investigate why, so I can decide whether to sell or buy more. If I could add links for research sites like my preferred charting site, fundamental analysis site and due diligence site (Barchart, Stockopedia, MarketIndex) it would be a significant improvement. What happens now is that I have to navigate away from this site and rarely return after the first investigation. It would really set this product apart from a crowded market if this was a Stock Portfolio Portal instead of just another portfolio register. If the see merit in this I would suggest adding the provision for multiple watchlists so the app becomes the gateway for all things stocks.
