You may have already addressed this, as I just downloaded the Beta today and have only gone through the tuts. Since I didn't see these mentioned, I thought I'd touch on them.
In the tut on Text Styling, it explained changing a text or character style using the 'Update Paragraph Style' button or the 'Update Character Style' button. It struck me that it might be helpful if one could create new styles (both paragraph and character) in addition to just changing an existing style.
It would also be helpful if all styles could be exportable/importable, so as to be usable in other documents than the one in which such new styles are created. Also/Or, if any newly created styles could be allowed persistence in the app's installation once created, it could save a lot of production time and effort.
Just thinking aloud.
Thanks,
