The coveted Journal skin.
While there are many great skins out there for Premium Members to use, a lot of deviantART users wish they had their own, but lack the coding knowledge to do so. So I came up with the idea to allow the users who do not wish to learn, or cannot grasp a new language to customize their skins.
This is a very basic example of an option I would love to see included. Users don't always need huge, fancy journal skins, they may just want to edit the default one a little. So this simple example shows how it could be done. Whereby a user would simply need to input words which could then be translated into CSS for the journal HTML.
The range of options could be increased, and there could be a lot more freedom, but I certainly feel this would be a great addition to dA so that users can make the most of their premium membership!
