If you earned enough interest that it was the sole reason you logged in every day, you are part of the reason it needed to be removed.
Personally, I liked it better the way it was. I'm not big on change, though, so perhaps it's just something I'll have to get used to. And hey, maybe then I'll even like it better.
I like the fact that the pages are combined now, but the up/down arrows when depositing or removing sP are rather rediculous? Who would use them to go up 1 sP at a time? I also miss that before, when you clicked on the empty field, it gave you the options you previously deposited. It was quite handy, every time I go above a certain limit, I deposit 1 mil into the bank, now I have to type it out every time.
