It bugs me that the first domain added to a subscription my have their files located in the directory "httpdocs". I can put subsequent domains in more relevant directories, eg. mydomain.co.uk in the directory "mydomain.co.uk". Being able to change the default directory name from "httpdocs" would make it easier for new customers to find where they should put their files. At the moment, I create a dummy domain name, and always add my customer's main domain as a second domain, and into a directory named after the domain.
