Display app prices (and $ total?)
If possible, can you add app prices in the paid list?
And as a bonus, a grand total of how much all the apps cost?
That'd be fantastic.
This is possible, however the price Google includes in their HTML markup reflects the current price of an app.
This may become confusing to others, since many apps may have been purchased on sale, and that sale price will not be returned. If you ever want to see what you actually paid for your apps, I'd suggest signing into Google Wallet, which stores the actual price paid.
I may still include your request (if I can figure out how to), and just place a warning next to the tally indicating, price does not reflect actual purchase price.
