This is a must-have feature for me coming from mint.com.
There's an existing Notification for "Bank Fees" over a certain amount (defaulting to $5), but it doesn't meet my needs.
I'd like a notification, by category, for all "fees". Some examples, a wire transfer fee of $15, a $7.60 margin loan interest in a brokerage account, or a $99 credit card annual fee did not trigger any Notifications for me with the $5 "Bank Fee" setting turned on.
It doesn't have to be real-time, but same-day would be good so I could have time to take action on them.
