We already have 'Text'. Is this different or could we reuse what's already there.

Just checking: the 'Paragraph' isn't just a FlowPane with special support for line wrapping text is it? I.e FlowPane.setWordWrapEnabled(true).

I feel like the word wrapping text+embedded objects is the big thing here, otherwise it's just a flow layout right? I don't really get an immediate sense of what this is all about from those samples. Most of those screenshots could be achieved without a new paragraph tag I think. 

Perhaps it would be good to see examples of wrapping in this docco - basically a 'page' of text with a couple of paragraphs with some markup in each (span, hyperlinks), and some images. Maybe screen shots of the same screen in different sizes so wrapping is clearly visible. 

I do think it would be good to control the way text wraps around embedded objects (eg images) from the get go and demos of that would then be great. 

What about the other markup bread-and-butter tags: ul, li, blockquote. Are these on the list for consideration? Some way of doing this (eg additional Nodes for these) would seem useful.
