Arlo Rose and Perry Clarke have released Konfabulator 1.5, an update to their JavaScript runtime engine for Mac OS X that lets you run small files called Widgets. Version 1.5 adds over 200 new features, including support for drag and drop, direct text input, keyboard events, mouse event tracking, and better desktop integration. In addition, the default Widgets were updated and five new ones were added. The software sells for US$25 and requires Mac OS X 10.2 (Jaguar) or later.
