The new version will add it back in, technically it was a bug to begin with. I haven't figured out how to hook into the internal undo code.
I'm in a code freeze pending some internal bug testing, once that's don't we'll release it. If you send me an email I'll send you a copy of the (possibly a little buggy) latest version with the writeback feature back in.
