Most of the time I purchase multiple DVDs at a time. The store receipts have individual pre-tax prices and a single line for the total tax. Thus, when I enter the price info into DVDpedia, I have to calculate the total price paid for each entry. I'd like the option for the Pedias to automatically calculate the total purchase price (the "paid" field) including local taxes. I'm thinking that a "tax rate" field could be added to the preferences along with an option to enable the calculation.

ETA:
I'd also like the local currency symbol to be added automatically—I wouldn't imagine that this would be too hard to implement since it's already set in the System Preferences

Thanks!
