Well, I'm not sure I agree.  Just because there is now an in-game bank does not negate the funds widget, although perhaps the original use of it (to track funds given to an individual) is now void.  By the same token you are saying the bank widget is also not necessary, but I think that can be useful on the website for people to review at work or while the game is patching, etc.  

The in-game bank only tracks things for a certain time, and I think it would be nice to be able to have a more permanent record of everyone who has donated to the bank.  Unfortunately, this was the first bug I bumped into on our site and did not quite realize how long things take to get answered on here, so now I have already lost a large list of people who initially assisted with getting our second vault, etc.
