It would be nice to be able to create styles for the buttons and forms so you don't have to manually adjust it when your document has heaps of the same fields.
Even just being able to change the default settings would be useful. I have to waste so much more time having to manually change each field setting.

Who decided that Minion Pro, 12pt and scrollable was what people wanted?
Also, why would a checkbox by default be checked, most of the time you want a checkbox not to be checked when creating a form??
