Allow additional text (like bylines) on Title and Header 1 cards
The title slide only offers one text field, and the caption is hidden if you set a background image. It would be great if you could add a little bit of additional text (date, version, authors, etc.) to give some more context to the title slide.
Heading 1 cards are equally limited. Since I have to have a Heading 1 card in order to be able to use Heading 2 cards it would be nice if I could put a little more contextual information on the Header 1 card, especially for sways that only require one Header 1 card (single topic). Leads to redundancy.
