This is very exciting. Following on GitHub & anxiously waiting for the demo video to finish converting.<p>However, doesn't this go slightly against Jolley's idea[1] that the tools should be free and available to everyone (including Linux and Windows users)? I understand this is not the de-facto tool for SproutCore development, but do you think that making an Interface Builder clone with SproutCore itself is a viable option? It would have a lovely meta-feel to it, like the Rubinius Ruby interpreter being written mostly in Ruby.<p>Neways, kudos for releasing the project. I'm going to try it later when I get home.<p>[1] <a href="http://blog.sproutcore.com/post/756343010/the-next-revolution" rel="nofollow">http://blog.sproutcore.com/post/756343010/the-next-revolutio...</a>
