Dashcode has been rumored to exist for a while, but now we know for certain: it’s being bundled with new MacBooks, and some kind soul sent his copy to Cool OS X Apps. It’s way more robust than I expected. Breakpoints, easy interface building (complete with a library of “ooh shiny” components), a GUI for your widget’s PLIST file, and built-in localization. This is awesome. I really ought to start working on version 2 of my Azureus widget.
