VPS disk usage must be shown in accounts list

Its a really basic feature that should be shown directly beside the disk quota. It´s real bad UX, that a button must be clicked and then a hover is required to see this, and it´s needed account by account. Also, an account with disk quota full doesn´t alert in anyway. This is a MUST in a reseller or VPS. After using sPanel for a couple of weeks, I see that for regular users it´s really good, but for resellers and VPS it´s lacking tons of really useful features, and some that are real basic such as this one.
