Again, similar to the Accounts/Google section – once you load this tab you’ll be greeted with a similar page, once again click the “Add Account” to get started. This will bring up another pop-up asking you to insert your PayPal email address and password along with asking you to select the proxy group you wish to use for all PayPal requests made by that account.
When finished you’ll see the following two icons beside your account in the column:
The left play icon will open a browser allowing you to login to your PayPal account. This is especially useful when you want to create a PayPal session in advance to a drop. (Replaces the "PayPal preload" feature known from 4.0)
The garbage icon will remove that specific account from your list.
