This just came up in my mind and I assume this would help alot of players.
If your current rebuy cost would exceed your current balance and be forced to take a loan or even lose your ship upon destruction then I suggest showing the current balance and/or rebuy cost in red in the right info tab.
Optional: Show it in yellow if it is close to be lower than the rebuy cost (around 10 - 15 percent).
This would probably be very easy to implement and wouldn't require much time.
