First: listbuilder rules, thank you. Being able to produce really NICE looking tables with so little typing is wonderful. :)
Second: A question. Is there some straightforward way to pre-check some of listbuilder's checkboxes? I'm pulling rows out of the database and would like to check some of them based on a value pulled from the db. Feel free to point me at a package that does this already if one exists. I've looked at the docs (thanks Jade) and api-doc but am not seeing anything that seems to do what I want.
