Stage is a JavaScript widgets library that allows you to define widgets as collections of "entities" on a "stage". This will help you focus on the widget's behavior and forget about the hardcoded offsets and object grouping.
The library allows object positioning, dragging, resizing, aligning and grouping and supports as of version 1.1, labels, inputs, backgrounds, borders, lines, polygons, pictures, rollovers and animated sprites.
