Howdy! Are you planning on Desktop support for the UI builder? I was about to hand you all my money but it doesn't like it exists yet... or at least allow me to set custom dimensions on the editor/preview. Also, does it support rendering/previewing custom widgets? FWIW-- I've done a fair amount iOS development and loved IB (despite all the crashes and issues) for the easy visual editing; so, I'm primarily looking at this as a way to better visualize and layout my components (I personally don't need incredibly robust desktop support). Thanks for the work on this it looks awesome.
