Precious Metals Tracking
Simple way to track gold & silver portfolio value by inputing ounces of each and updating based on current spot prices.
Differentiate between "good" and "bad" debt
On the net worth page and any other places where we might conflate liabilities, it may be worth differentiating between the good & bad debt.
Richer support for tracking loans/mortgages

Lunch Money knows how much I have in each investment account, and it also knows how much I'm putting into each account each month (via transactions), so it could do a subtraction to find out how much money each month my accounts gain/lose due to market performance. (this is probably the only thing I ever check the Vanguard website for anymore, and it'd be really cool to have it in LM too)
