I'm trying to remove a page from a category. When I've looked up how, the only answer I've found is to enable something called a CategorySelect tool, apparently allowing you to delete and modify categories while using the editor. The problem is, when I go to Special:Preferences, the only thing I can find related to categories is "Disable Category module", which didn't solve my issue.

Secondly, I'd also like to know how to delete a category and leave no trace of it (does this happen when there are no more pages in it?), add categories to be shown under the Wiki Content tab (sub-tabs), and how to add tabs (example of tabs: On the Wiki, Wiki Content and Community).
