 The Posts and Pages lists show a status column for every target language, including the latest successful translation time and a translation action. The Settings page also provides **重新翻译所有内容**. It shows a confirmation warning before scheduling a forced refresh of published posts, pages, categories, and tags; this bypasses persisted translations and consumes Baidu API quota.

+The Settings page also shows a live progress panel. It refreshes every five seconds and counts completed post/page and category/tag items for every configured target language. When **重新翻译所有内容** starts a batch, progress resets and counts only translations completed after that batch began, so historical translations do not make a new batch appear complete. Progress reads only local WordPress and translation-table data; it does not send additional requests to Baidu.
