It stays in the pulldown from the homescreen. I assume it is to let you know its running. Option to not have that would be cool. I am particular about those things, I don't know why.
I know its running, I opened it and signed in. I don't need to be reminded. Would be fine if it were a short task being run and it let me know it has finished, just don't want it there all the time.
Blame OCD I guess.
