I'm not sure I totally agree with a conclusion that because one person was unaware of something it indicates a UI failure. ;)
The above was just a comment in passing. What my real reason is for posting to this thread is to perhaps make a suggestion. I think E Franco makes a nice suggestion. Basically, what I personally interpret as being asked for is more flexibility with the Step tool. And I have to say I agree with that!
What would be way cool is if we could group elements, then save the group to the Quick Styles. As you add the group from Quick Styles, the number or letter should increment. This would save lots of time and easily provide for infinite variety.
