Could use imorovements

Generally a good app, but for the very high price of $1.99 I would like to see better touches.

No scan / frame lines while scanning, app does no show if its focusing.
A better beep sound will be nice.
Cannot save QR code directly to photo library.
Editing of created QR codes will be welcome.
A short footnote on creating QR for SMS, telephone number, URL, web addy, vCard and me cards will be handy.
