Engines are added to `categories:` (compare categories), the categories listed in `categories_as_tabs` are shown as tabs in the UI. If there are no active engines in a category, the tab is not displayed (e.g. if a user disables all engines in a category).

On the preferences page (`/preferences`) – under engines – there is an additional tab, called other. In this tab are all engines listed that are not in one of the UI tabs (not included in `categories_as_tabs`).
