The ability to easily add the default BTO configuration in the Ajax bubble would be an incredibly good idea, especially for computer sales stores!

That way, a potential customer could see the default processor, RAM, etc without having to click each individual system.  Honestly, if I could make only one change to product cart, that would be it!

Another great change would be to add the BTO config to the actual configuration page, perhaps even in a floating menu script.  If someone is configuring a computer with 40 different options, they might like to take a look at the original configuration and perhaps see the changes to that configuration as they click a different option.  It sums it up nicely and would look gorgeous in a floating menu script.  But even a static table with the BTO configuration on the actual configuration page (I could never understand why it would be on the viewprd page and not the config.prd page) would add a great deal of value to productcart.
