It would be helpful if tools, like most other things in the hub, could be hidden or public.
Access to most content on NCIP Hub can be regulated by the owner/submitter or group manager. For examples, Resources can can be made to belong to and private to a group. However the ability to control access to a tool is not available. Currently, all published tools are public. It would be helpful if the owner/submitter of the tool could control access levels.
