As someone who sells Linden dollars daily (sometimes even multiple times), it used to be very helpful when the US dollar balances showed a negative value to easily know how much it takes to get into a positive USD balance. I understand it is confusing for at least some and there is a fair chance of missing the '-', which might have been the reason for this change. But now, unless you go into 'Account Summary' and 'Account History', there is no way to see how much your dues are. So I request that the Balance Due amount be added to the LindeX Pages - Buy, Sell, Lindex History so we can plan things easily.
Thank you for your time and attention!
