I see more hosting providers offering a mobile app for their control panel. It would be nice to have an iOS/Android app that let's you easily access Control Panel settings "on-the-go" such as Site Usage (Disk Space, Bandwidth, Memory, CPU Time, HTTP Requests, Historical Usage), Site Tools (Recycle, Stop Site), Settings, etc. An app would help attract more customers and may help retain existing customers.
We made the Control Panel responsive so you can access everything from your mobile device the same way you would from the desktop. It's not the same experience as a native app, but functionally it's all there. We considered an app, but decided the development resources would be better spent elsewhere. That doesn't mean it will never happen, but it isn't likely to happen any time soon.
