Hi there, I recently wrote a plugin to allow an 'onionskin' view of inkscape layers to aid animation.
I'm developing some other animation-related plugins, too. 

Someone told me I should let the Inkscape dev team know about it, so here I am.

All the info is here: http://github.com/lingo/inkscape_onionskin

Kind regards,
