I love this app and would have given it a 5 if it would do two things:
1) link or somehow sync to an online calendar, specifically importing to gmail calendar.
2) notifications. Setting them up for reminding of a due date AND date to pay (reminder to pay on a pay date)
The set up of this app is really easy to use, it has overall really great and easy to use features. I think if they could some how bring ins suggestions itd be a 5 star app no problem...or offer it as an add-on for a specific amount. Id pay for that.
