If you go to "account" and "Item List", it will produce an individual list of your purchased items instead of by invoice. I wish it was like that in it's default state, or that we could set it and have it show like that all of the time. As for updates, if you click "Item List", to the far right there is a column that shows if there are any updates for your purchases.

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
