What i find missing in all of the expense tracking application is automatic currency conversions.
As a traveler that changes currency allot i would the application to update daily on the currency changes and will reflect it in the report. (everyday is a new rate)
Another option that is missing is the ability to add 4% to the cash payment to inflict the conversion charges and a 2% to credit card charges.
For this purposes I use this site
http://www.oanda.com/convert/classic
i wish they could just integrate thoe options if the site into the application.
This will then make it a killer application for someone outside of his own country.
