The following [filter hooks](https://developer.wordpress.org/reference/functions/add_filter/) can be used to customize the output of action hooks and other functions without having to modify said functions. Filters can be easily added or overwritten in child themes or plugins. This list is probably incomplete. See `includes/functions/hooks/`.
This is an example of how to add a link to the subscription popup menu via the `'fictioneer_filter_subscribe_buttons'` hook. The link will feature a [Font Awesome link icon](https://fontawesome.com/icons/link?s=solid&f=classic) and be added in first place. Note how the link is pulled from the author’s meta data, which you would need to add yourself as it does not exist outside this example.
```php
// Add this to your child theme's functions.php
function child_theme_extend_watch_buttons( $buttons, $post_id, $author_id ) {

**$output:**
* $title (string) – HTML for the story title `<h1>`.
* $meta (string) – HTML for the story author(s) meta row.
**Parameters:**
* $story_id (int) – The story ID.
* $story (array) – Array with story data from `fictioneer_get_story_data()`.
Filters the intermediate output array of the `fictioneer_get_subscribe_options( $post_id, $author_id, $feed )` function before it is imploded and returned. Normally accounts for Patreon, Ko-Fi, SubscribeStar, [Feedly](https://feedly.com/), and [Inoreader](https://www.inoreader.com/).
**$buttons:**
* $patreon (string) – Optional. Link to Patreon if set for post or author.

Filters the groups passed to `fictioneer_get_taxonomy_pills()` before they are looped and rendered, allowing you to limit the number of taxonomies or randomize the order, for example.
Filters the source array of selected translation strings used in the theme, see `fcntr()` function in `includes/functions/_utility.php`. You cannot translate the whole theme with this, but give it a personal touch.
Same as the `fictioneer_filter_translations` filter, but only applied once when the `fcntr()` function is first called and cached in a static variable to save system resources. Using this is recommended if possible.
Filters the intermediate output array of the `fictioneer_user_menu_items()` function before it is imploded and returned. Contains links to the user’s account, reading lists, and bookmarks as well as the site’s Discord, site settings modal toggle, and logout link. Used in the `partials/_icon-menu.php` partial if the user is logged in.
**$items:**
* $account (string|null) – Optional. List item with link to the user’s account.
* $site_settings (string) – List item with site settings modal toggle.
* $bookshelf (string|null) – Optional. List item with link to the user’s lists.
* $bookmarks (string|null) – Optional. List item with link to the user’s bookmarks.
* $discord (string|null) – Optional. List item with link to the site’s Discord server.
* $logout (string) – List item with link to log out of the site.
Filters the check result of whether the user’s Patreon data is still valid. Because there is no continuous connection to Patreon, the data expires after a set amount of time, one week in seconds by default (defined as `FICTIONEER_PATREON_EXPIRATION_TIME`).
**Parameters:**
* $valid (boolean) – Result of the check. True if valid, false if expired.
