While this is already partly exists, I would like to propose an extension of town bank balance updates.
In addition to notifications when /t deposit and /t withdraw are used, I think we should add a message that says the net gain/loss from the bank after taxes and upkeep is processed. This would help mayors (like myself) better manage their towns and may reduce the number of people quitting as a result of their town collapsing.
I also think it would be nice to have alerts when money is spent from the town bank (I.e. When claiming a new plot).
Maybe these notifications can be toggleable?
