I have a few pluspoints, but really, I get so much interest, that after one hour my bank is full again, I understand why you would want to use the pluspoint system, but I really like to collect money, and well, I'm currently at 400 mill and of course it's enough to buy and do anything I want to, and the being-able-to-bank-everywhere rocks, but it's just never enough anyway, mankind id greedy, that's all there is to it. I'd like to see moneylimits removed and interest removed.
why remove the interest? Because otherwise you can make a living out of it, I hardly ever refill my bank if I take a few mill from it, because one hour later it's full again anyway. I don't know if it's a problem to code something like that, of if the server may go crazy when people start having 10's of billions on their bank

But otherwise it would be neat, maybe also make moneymakign harder, you can make a mill a minute with only two props now.
