Updating the OpenBabel node

Hi,

I would like to be able to convert INCHI to molecules in Knime. OpenBabel 2.3.1 can do this, but the current openbabel node is based around an older openbabel version, and can't. What's the best way to update the node, or should I just write my own node to call openbabel from the command line?

Thanks,
