Online drawing editor and svg UI components

Hello,
 This is my website editing SVG document: http://www.svg-editor.appspot.com/ http://www.svg-editor.appspot.com/
 as pointed by http://www.drawsvg.org/ http://www.drawsvg.org/
 It differentiates by wysiwyg interface written in svg.
 Try and make me your feedback.
 I propose to provide in the form of an open-source project of the svg components (slidder, checkboxes, lists, ..) of the site.
 Is anyone interested?
 The components are inserted into the document in a declarative mode (Elements svg, css, javascript behavior).
