Thanks, Ian  
Next question, :) – In the doc, some images require headings/titles and a caption, but there is only space for a caption. Adding a section header will put it in the sidebar, which is not ideal. So for now I've added a text box above the image, because there is space for a title there, could you add either a title field on images or a simple Title row (which would not end up in the sidebar)?

Laura you should be able to put any text styles into the regular paragraph area. If that doesn't work, I'll create a new block type, or like you said, add a title field to images.

Show options…
Actually - I think it would be neater to include the title on the image
