deviant Sidebar
Everything has a sidebar these days, from applications to websites... and the reason is just because they're so damned functional. Choosing one for deviantART was only logical. I picture everything below the "Avatar, Name, and Stats" sections being closable/hidable, reducing them to simply the green bars with the titles.

My Quick Links
Not a stretch from the Navigation bar up top (in fact it's really no different at all, barring the look), but I think having them more centered allows them to be more useful, and when used in tandem with the Navigational icons above, you can then double the amount of actions you can make within deviantART. Or, for those of you who may not like the Navigation icons above, hide them all and simply use your Quick links in your sidebar!

My Control Panel
for all this stuff, you've got to have a place to house it. Enter the "Control Panel".

Profile Module Management
Think of it like iGoogle, My Yahoo, MySpace's internal modules, or your profile on Facebook. Arrange your entire Profile page (by module) how you like it, restricted only by columns. Your choice of two or three column layout. But then, imagine you can make public or private any module you like, as well as take advantage of a "minimize" feature in the event you'd like to have them all available to the public but are worried about it looking too cluttered with them all "open".

Deviant Power Mode
All of these are for the most part self explanatory, and not unlike the items above, would all be easily turned off and on with the click of a box. I do want to touch on a few of them, however.
Power Tutorial: basically, dA tutorials that are integrated to encompass an ultimate link and module augmentation multi-tool. The goal would be to provide deviants with excellent previews, useful extra information, and relevant next actions for almost any given link, section, or module on any given page.
Power FAQ mode: Just like the tutorials above, and relevant place that a deviantART FAQ might apply would create a mini pop-up window displaying the appropriate FAQ links----and perhaps even the Question prefacing the answer.
Condensed Journal: cut the available front-page text to half of what it is and offer a "Click here to read more" option at that stopping point. Many people loathe scrolling down a long page.

Collections Module
I felt this was very important to add, because as it is our recently collected Collections are shown NOWHERE beyond going into our favorites gallery. It would better our experience, I feel, to have the option to display these. Let's face it, Collections rock!

More, More, More
I've made more room for displaying more things in this design, such as Recent Deviations, Submitted News, etc. And while it seems as though I've cut down in other areas, such as the Wishlist, i have in fact presented them with the ability to Browse directly from the profile page, from first to last, one at a time. This is the same idea with our Featured Deviation.

UPDATED:: I changed the color of the little arrows next to the names of the sections. It was hard to see the white color. The three, large, non-essential sections (Tools, Resources and Groups, would be able to be minimized, and would be minimized by default. Users wishing to ignore these sections would be able to easily.

On top (Submission) window
- Ability to minimize some sections. (Tools, Resources, Groups)
- Addition : Once category is selected, the "Tools" section would become active under that category. (In this example, Digital)
-Tools Section-
-- There would be three columns. ( Frequently Used, All, and Custom)
-- Frequently used would show the selections YOU frequently use in THIS category. (Digital)
-- All would show a large list of selections popularly used under this category. (Digital)
-- Custom would be used if your desired selections are not available. Here you can construct a personal list of custom tools for all categories. ( This is not category specific because you may use some of these for more than one type)

Below the Tools Section would be Resources
-Here you can easily give credit to stock owners, textures, and models.
--The first part of this section would be "Resource Credit"
-- Here you could add a deviation by URL link, or thumbnail code, or you could click "Add from Collection".
--::Add from Collection would open a pop up window, much like when submitting directly to a group gallery, where you could browse your favorites and collections to select the resources if you had favorited them.

-The Custom section is for any source needing credit OUTSIDE deviantart (Such as google images, or another stock site) or deviants within the image. (Models or Collaborators)

---

In the second image
The deviation page. On the left hand side, with the other piece's information would list the tools used, and any resources or deviants that took part in the piece.

--Clicking a tool would open a search page of deviations made that also tagged that tool.

--Next to resources used, (this will be visible only to the artist, like the "edit" button) there will be check boxes, and above, a "Notify" button. When pressed, it would send a basic note to each of those deviants. It would say that you have used their stock, link to their stock, and then a thumbnail to your deviation. Once you have sent this notification to them, clicking that button again would prompt, "You have already notified these artists. Are you sure you wish to message them again?".
