Add the ability to show projected dividends by month, and week for the next year based on the stocks, bonds, CDs, Money Market, et. al. in your portfolio. You should also be able to see these by account type to determine potential tax implications.
A good start would be to add the Ex-Div and Pay Date to the current 'Portfolio' on the Investing dashboard.
An Investment Income view on the 'Investing' dashboard would be nice. It would show a bar graph by month for the next 12 months based on your current portfolio. It should also show the average income per month.
