Fair point. The spacing and margins are totally wrong, for sure. But that's just spacing & margins, and I assume that's easily adjusted (and they should do that, so their demo doesn't look ugly). But nonetheless, the widgets are native Cocoa widgets, so they not only look native, they feel and behave native, something you can't say about Qt (at least not to the same degree — although I develop with Qt, love Qt, and have zero issues with the way Qt applications look and feel on Mac).
