update cart of check-out page

I searched some days and found your plugins more better than others, so I bought from you both this plugin and free shipping plugin today. I have a problem, you see, when free shipping order meet the min. amount, the free shipping plugin will say:” congratulations, you have got free shipping, pls go to checkout. “, If the link of “checkout” is clicked, the page will go to checkout page of woocommerce. When I use “Cart all in one” plugin, the checkout can be done directly on it, no need to go to checkout page of woocommerce, more importantly, when I minus or add quantity, the price will be updated automatically on “cart all in one” plugin. So, in order to uniform the function, what we normally do will disable the checkout of “Cart-all-in” and lead customer to “checkout”page of wocommerce, but as you know, for the woocommerce checkout page, when you add or minus qty, the price cannot be updated automatically, so, can you help me out and make woocommerce checkout page achieve the same aims as your” cart all in one ” plugin does, that is, the price can be automatically updated when adding or minusing qty, instead of clicking “update cart” button of woocommerce checkout page.?
I know my requests may be out of your service scope and will require some codes to hide “update cart “button of woocommerce” and make price automatically updated, but I still take the liberty to ask for your help. Your help will be highly appreciated. Thanks in advance!
