Illustrator Layer to SVG Exporter

layers_export.jsx

/*
 * Layers to SVG - layers_export.jsx
 * @version 0.1
 * Improved PageItem selection, which fixed centering
 *
 * @author Anton Ball
 * Exports all layers to SVG Files
 * I didn't want every layer in the SVG file so it first creates a new document
 * and one by one copies each layer to that new document while exporting it out
 * as an SVG.
 *
 * TODO:
 * 1. More of an interface wouldn't hurt. Prefix option and progress bar of some description.

Thank you! That thing is super handy, also only one that works properly!

Thats amazing :)

this works perfectly. Thanks for sharing it.

Script works perfect, thank you! Is it possible to add an option for scaling? I'd like to export the artboards to 200%.
