Is there a way to disable the built in data lists? Right now it displays all the available data lists defined in the data model.
If not, the best option would not be to make available lists a share server config option, but rather make it a configuration option for Site Managers to include available lists (by default no lists should be set to available). What needs to be available may differ from site to site.
I'll be happy to add this to JIRA as an enhancement request if there isn't anything like this yet.
