When adding a record to the cart from the result list, the entry changes to "In your cart (remove)", but clicking on it again doesn't change the label back.
Just realized you have to click on the 'remove' part. :) When you click on 'in your cart' the message about items in the cart flashes really quickly. Maybe we could improve the usability a bit?
Another small thing: when scrolling down, the floating toolbar can hide the cart messages.
