Widgetarium is an IDE for creating Dashboard Widgets. It includes the following tools for making it easier and faster to create your Widget:

-Syntax Aware Editing: Editing your source code in an environment that provides language sensitive color, code completion, popup functions for easy navigation, split panes, full search & replace (including regular expression support).
-Project management: Project file keeps track of all your sources, images, and any other file that you'd want to include in your Widget. It then correctly builds the Widget, setting all the various flags in various files correctly, copies the source files to the correct place, and can install the widget or compress it for uploading.
-Dashboard Emulation: Instead of having to run your Widget in Safari or having to constantly kill/reload in Dashboard, Widgetarium provides a built in Dashboard simulator right inside the project. Your Widget code runs just like it would when running in Dashboard.
-Widget Inspection: Besides running the Widget, you can also inspect the Widget itself.
-JavaScript Source Level Debugging: Widgetarium provides a full source level JavaScript debugger, allowing you to step through your code (including "step into calls", "step over calls" and "step out of routine"), set break points, see stack crawls, and view/edit local and global variables.
-Graphic Tools: Widgetarium makes it easy to create the basic graphics you'll need to create a Widget. From making the basic panel graphic (in various styles, custom colors, shapes, sizes, including the special "weave textured" back) to special button graphics and the Widget icon image.
-Ready access to Documentation: There are handy links to a built in document browser that gives you instant access to Dashboard documentation and other related programming documentation (requires either XCode installation or an Internet connection).
-Quick Start Templates: Widgets can be created from a starting template, which will make the basic files, images, and standard behavior a Widget.
-Special Extensions: Widgets created using Widgetarium have access to special additional routines to perform a wide variety of actions not available to JavaScript.

Requirements:
-OS X 10.4.4 or later.
