I am currently using UC Node Checkout module to essentially post classified ads. I would like to duplicate the feature in the full cart within the block cart whereby you can click a link of the title of the ad to edit the node or delete it entirely from within the block. I've tried hacking the module and uc_cart_block_content to create links to node edit forms in the cart block with no luck so if someone else out there thinks they can do it please get in touch. Also, if you need more information please contact me.
Regards,
Ian
