For a UI toolkit, they don't seem to parade all that many screenshots (or maybe I didn't find the right page). All the examples shown are from audio software with pixel-precise design.<p>Fancy gradients, photorealistic knobs and tiny text labels are certainly the right choice for this type of applications (it's actually pretty interesting how certain software niches have instantly recognizable signature looks which all the vendors within that space share as if bound by an unspoken agreement). But I'd also like to know whether Nui can handle flexible layouts, long text paragraphs, user font preferences, accessibility concerns, tabbing between controls, etc.<p>In a way, Nui seems like an "anti-GTK+", in the sense that GTK+ tends to look very plain and can be difficult to customise for pixel-perfect layouts, but does fairly comprehensively handle all the boring usability and layout automatisation stuff.
