One question: is the layout of the widget customisable? I.e., mainly the font and colours? Because while the “splashy” comic-style makes for a refreshing change on the one hand, I could imagine it might not be appropriate in all contexts.

The same is true, by the way, for the entire landing page and the docs. It looks fun and distinct, but I also had some slight troubles to parse the structure and find my way around.
