currently you only allow a single plan to be applied to all domains within an account.
Please change this so that each domain can be on a different plan.
e.g.
domain 1 (basic plan)
doamin 2 (plus plan)

Most of my clients are not technical or computer literate so have no interest in having their own login, I manage everything for them, so put all domains under my own account. But not all clients/domains need the same plan.

Also even with having clinets on their own aoccunt/login, some have multiple domains. The primary doamin might need the plus plan but secondary domains only need basic plan.
