Spending Comparisons Between Months

Have the app allow for spending comparisons for example, at this time last month you had spent £44 this month you have spent £39.

this would be in total and per category so you can see whether this month you are saving more than last month.

xurrentl you can see the overall spend in total and for each category but comparing to previous months is not easy unless you flick from month to month.

I know wasnt created to help with saving but it would be a useful feature to have.

What do you think?
