The Inkscape Community Announces 0.48.2 Release, August 14, 2011
One of the recent releases of Synfig Studio, an excellent free 2D animation editor, already featured a basic SVG importer. Since then the Synfig's team has changed their mind, and now Nikita Kitaev is working on SIF exporter for Inkscape that will functionally replace the SVG importer in Synfig. If you are interested, fetch the extension from Github and tell Synfig developers how it worked for you.
