One thing that would be nice to see in combination, though it may be well out of the scope of this project and/or a wild difficulty in coding up: An option/link in the wizard that is something along the lines of "view this layout (with this theme and these columns) in live form". It's not always possible to tell that a layout puts a big border around blockquotes or changes all the bold tags to bright pink or whatever. I've set up a test journal with variations on every possible post I usually make (long subject, no subject, off-square icon, quotes, ordered lists, etc.) so that I can see what any given style does, but not everyone thinks to/wants to do that. The current form of "preview this style" is not very helpful in that regard, especially on a new/blank journal.
