In Compile.
This is a problem.
The text in the editor, in my experience, is rarely uniform.
Even when I set a default font and size, even when I transfer text using “Paste and Match Style” line spacing is sometimes wrong and unwanted artifacts unexpectedly get brought over.  
You never had to worry about this before, since Compile fixed all these problems.
Compile was the soul of Scrivener.
But now?
How to establish uniformity amongst text in different files?
Does Compile give an answer? Open the Compile panel and there are no defaults. That is, the default is blank:
"
What if there are no section types? Now what? When drafting a document you don’t always know what the ultimate structure may be. The structure of a novel is usually–though not always–relatively simple, but there are dozens of other examples of books with intercalated chapters, sidebars, and what have you.
In an appellate brief, is a statement of font and font size front matter? Probably. But are you sure? You can start writing, or futz around with it. Or look it up. Or post on the forums. I’d rather start writing. What about Summary of Argument?
A table of authorities? A Mini-ToC listing cases cited in this section? In a novel, a dream sequence which is part of, but typeset completely differently from, a chapter in a novel? This gave InDesign fits. When composing the document–and remember, Scrivener is the first draft tool par excellence–you will often not have the answer to these questions, if you even have considered them.
If you want to structure as you go along, write in LaTeX/Lyx: you are forced to put on the dress of the text’s structure, whether it is too tight or not. Otherwise you can’t go out.
This was never the case with Scrivener. Write away, compile away, and worry about the structure later. This no longer is the case.
