You have created a very nice and useful module and we will buy it definitely.
but I think you can improve its documentation , the current documentation is incomplete and ambiguous , for example in the module settings , when you add the server , you have said enter the IP address of the server and the username and password of server.
now we have 2 different things here , the server itself and PVA. someone may have the virtuozzo server , but not the PVA.
from what I understood here , instead the IP of server and username and password of server , we can use the IP of PVA and username and password of PVA for module server settings.
it is not documented in your website.
