A few details of Flash 5 have filtered out from the Flashforward 2000 conference, as well as other details about the future of the animation technology. The first major change revealed about Flash 5 is that its interface will become "more familiar" to professionals – so expect to see a front-end with Adobe-style tabbed palettes. Also shown off was a ‘widget’ builder for creating reusable objects. Macromedia has also opened up the Flash player’s source code by releasing a SDK (software development kit) for the player. This includes a fully uncompiled version of the player in C++. This is designed to aid the porting of the player onto wireless devices, set-top boxes and the suchlike. The SDK is free and available for download from the Macromedia Web site.
