I was hoping to use this module to create "create here" links to create nodes with preset category associations. Unfortunately the interface does not allow for this to be done since there is no way to specify a query string as a default for a value that is chosen via select box. This means that categories can not be set based on query string variables, which is unfortunate as it would make this module very useful.

Thanks for the work so far, I'll try to take a stab at creating a patch if I've got the time.
