It would be awesome if there were a quicker way of marking a bill "PAID" by maybe swiping the bill to the left as if to delete it and there being an option to "MARK PAID" also, that worked in one step, marking it paid and saving it. Now you have to tap it to bring up the option to mark paid, tap mark paid, and then it brings up a new screen that you then have to save = 3 steps, which is 2 too many. Thanks!
