I can't believe I'm saying this, but the new update is [good or bad] BAD!
First of all, in the before, I have always found everything foey perfect.
Now, however, I see flaws.
The "donation field" took away my favorite button. Often, I only check in to use up whatever is left on the bar (to avoid it becoming full) and be done with it. That is why that button (the third donation button) is my favorite. Now, I can still just press "Use", the effect is the same as before, sure, but the button has a broken feeling -- only half of it remains and the other half looks like a hole (a blank).
It should have replaced the first button, the "Use 1 FP" button. OR, it should have added two other buttons of the same style as before, one for "Use 500 FP" and one for "Use 1000 FP" or something like that.
And yes, the "0" does not disappear when you click the blank, that problem too!

Retract that. The new update is GOOOOD! -- Because just now I input minus 345, that is, -345 in the field, and then pressed "Use" and 345FP was deducted from the target GB and returned to my inventory!
