Thank ya kindly. I will update it this week so you go straight to the "used books" selection screen, instead of the more general selection area.
I don't have any plans to upgrade it to use other services at the moment, because it is used by so few of people - I think it's better to be simple and easy to use, rather then more powerful. If there is overwhelmingly support the other way, it'd be an easy change though
Happy Holidays!
