Hi David,
Thanks for taking the time to explain with a video properly.
We added a setting to disable the cart page in fact since the cart page is redundant now that the cart drawer has all the features for the user to complete the sale. Feel free to enable it but all the extra features are in the cart drawer.
Also, when disabled if a user lands on the cart page it will automatically show the cart drawer instead, as seen on your video

Let me know if you have further questions
