I just tagged a version 0.03 release. It's available for download here:
http://github.com/downloads/codenode/codenode/codenode-0.03.tar.gz
The main reason for the release was upgrading to jquery 1.4, but there
are other javascript tweaks including the long awaited press backspace
in an empty cell to delete it.
Let me know how you get on,
James
