I installed the plugin.
In admin I see the option to add categories and tags. But it appears that all tags and all categories from my entire site's posts database are added automatically to each page by default.
It seems that there is no way to control which categories/tags are assigned to a particular page? I have multisite installed but it's not pulling info from multisite just from individual site and displaying every category and every tag that is assigned to different posts on each page.
