Allow restriction of tags to non-staff groups

It’d be nice to be able to limit these to other groups, as we don’t use the Staff group for our own team members.

This feature was added last week.

Now, when creating/managing tag groups, you will see the option to select which group(s) of users can use the tag groups that you have created. That can include the ‘staff’ group or any other group you have on your site.
