Display a pop-up (small) image of how the home page would look like when browsing the available skins.
It is difficult to choose a skin just by name or the (some times missing) skin sample image that is provided by the skin designer.
A welcome change would be to have an idea how the actual website would look like, without applying a skin.
Hoover the mouse above a skin, display the actual home page in small preview pop-up window near the mouse pointer.
Same would help with the containers and admin skin selection. Display a HTML/Text module with Ipsum Lorum and with h1/h2/h3/ul/p when hoovering containers or an edit page (from the HTML/Text module?) when selecting a skin for the admin pages.
