Emilio: So, I would definitely keep the category breakdown, current monthly expenses (maybe with a yearly/weekly switcher - I like that) and average subscription costs. Most expensive subscription (in one year - not by billing cycle!) would be interesting, too.

Maybe it would be nice to have an overview of each project. For example you could change the 'upcoming payments' list into a 'project overview' list. There you could list project specific statisics like monthly expenses, subscription counts, most expensive subs, and maybe the next upcoming payment of this project.

Thanks for adding my suggestions so fast btw! That's awesome!
