/*
 * Todo List:
 *
 * - Entries Admin page, make columns sortable, add order parameters to get* functions.
 * - On Page editor, have a postbox with link to the guestbook admin entries.
 * - BBcode: add width and height to images.
 * - Add Filter for get_entry_count SQL, like get_entries.
 * - Add filters similar to pre_get_posts.
 * - Add proper docblocks to filters in the code.
 * - Consider a functions/list-view.php refactoring.
 * - Consider SQL IN when emptying spam/trash.
 * - Someday, do something with the REST API. Someday.
 * - Unify statuses in one status column like WP_Posts.
 *   Add status 'private', only visible for author and moderators.
 *   Add status 'revision' to support that too. Add metabox to editor to restore old revision.
 * - More smooth import from third parties.
 * - Test and possibly add support for Gutenberg editor (shortcode block and widgets).
 * - Support sticky entries.
 *   - https://wordpress.org/support/topic/pin-entries/
 * - Support mark-as-ham for Stop Forum Spam. Needs API key.
 * - Do something to have less database queries for meta fields in add-on, especially export:
 *   - Use foreign keys for add-on, set meta var (add function). Test with frontend and export and isam db-engine.
 *   - Use foreign keys through a hook with SQL, and add a setter for meta.
 *   - Or add function to prepopulate metas for export.
 * - Support rewrite API for single entry and for paging. Look at bbPress.
 *   - https://wordpress.org/support/topic/search-engine-friendly-url-2/
 * - Use select2 or similar for subscribe/unsubcribe dropdowns.
 * - On one-page-design, paging doesn't work correctly in Chrome:
 *   - https://wordpress.org/support/topic/problem-of-text-selection-in-gwolle-guestbook/
 *   - https://wordpress.org/support/topic/gwolle-and-onepager/
 *   - https://wordpress.org/support/topic/ajax-reload-on-entry-pagination/
 *   - Using AJAX for pagination would solve this.
 * - Use more CSS transitions and SVG icons.
 *   https://stackoverflow.com/questions/15979235/css-transition-show-div-smoothly
 * - Use CSS classes from contactform plugins, when they are active.
 * - Use new capability options in WP_User_Query in WP 5.9.
 *   - https://make.wordpress.org/core/2022/01/05/new-capability-queries-in-wordpress-5-9/
 * - Automatically convert links and images to bbcode after cut-and-paste into the textarea.
 *   - https://zenoweb.nl/forums/topic/automatic-link-creation/
 * - Redo the "visitor from city wrote on datetime" into better translatable text with placeholders.
 * - Editor: really fix timezone issues.
