Please can you make it an option in settings to change the period that average spending is calculated on? I do not find three months useful, and would personally change it to 12 months. It would also be useful to see average spending over different time periods to help analyse spending. Here, you should be able to click on average (drop down type thing), where it would give you 3 month average, 6 month average, and 12 month average.
Thanks a lot,
