We love the easy design of our billing panel as much as you do, so this is why we have added a custom theme to our shared hosting clients what matches the design of our billing panel!
Have a look at the screenshot below:
Even though we have set this to be the default theme for all shared hosting clients you may need to clear your cache to get it. You can also use the default theme if you want.
At the moment all reseller (Master and normal) won't have this theme added yet. However, we are still deciding on whether we want to give resellers it as we know they like to choose designs and that them self :)
