Expand the Window Tile feature to allow Customizing the Individual Sections of each Window

I didn't see it in the documentation and I've tried to check the actual interface. It would be very helpful for those organized individuals who like to keep their windows (tools/tiles/etc) all in a neat order. So far we can display multiple windows in one screen and expand or hide certain section within each of those windows, but It would be helpful if we can customize each individual section. For Example, Separating the "Categories" tile within "Categories & Products" window apart from the "Products" tile into two separate views while still maintaining their dependence in-order to function as they normally do. Hiding the image tile under the "Categories" section can be hidden to just a small bar maybe 5px tall, which is okay, but removing the tile completely could be an option especially for those who use custom themes and the categories are assigned images through a different module outside of the Magento core files.

Or, for a much easier feature request (I think), would be to have the ability to drag these windows OUTSIDE of the actual interface window and drag each tool to a separate display. This is actually already possible, but only if the GUI is not maximized (in "Restore" view) and stretched over to the next display monitor which will allow full views of each toolset (Or Maximized across all monitors if the user has a technology installed such as AMD Eyefinity or NVIDIA Surround).

Are the skins open-source? Can we create our own skins for the UI? That would be nice too. I haven't looked into this so it might be currently possible.
