change all popup windows similar to login/signup



Stripe Connect payment Gateway:
Create a complete payment gateway module that will work in the following:

From the backend the admin will setup the commission that the site will take from each transaction and setup the api keys to connect stripe connect.

the vendor can connect to our account using “Connect with stripe" Oauth right after setting up a shop for the first time.

after that the buyer can add multiple items from different vendors
Vendor1
Vendor2
Vendor3
then pays the total and then stripe should automatically split the payment between all the vendors then deducts website’s commission from all of them.

any extra options on top of the mentioned features you can add in the this Module will be great.
