Couple things I've noticed which seem like items to be fixed in the qt client:

1. When clicking on a transaction to get details, the from field always shows 'unknown', though the information is certainly obtainable and is listed in the block explorer.
2. In payment requests, the balloon for the message field states that the message will appear when opened by the recipient's client but will not be sent with the payment. This does not appear to be true since I can't see where it's encoded. Also, why wouldn't it auto fill the message field in the recipient's payment screen? It could be useful for returning confirmation codes to prove a particular customer has a payment. However, wouldn't it also be better if the message was encrypted so that only the payment recipient could read it?

One last one, There doesn't seem to be any qr codes. They're intended to be added to the next release right?
