  Mattermost Deck は、Mattermost Web の使い慣れた画面をそのまま活かしながら、右側にマルチペインのデッキを追加できる拡張機能です。投稿、編集、チーム移動、スレッド表示などの基本操作は Mattermost 本体に任せつつ、必要な情報だけを並べて一覧しやすくします。
  
  Mattermost Deck is a Chrome extension that adds a multi-pane deck to the right side of Mattermost Web while keeping the native Mattermost interface as the primary workspace. Core actions such as posting, editing, navigation, and thread handling remain in Mattermost, while the deck helps you keep important information visible at the same time.

  Mattermost Deck is a Chrome extension that adds a right-side multi-pane workspace to Mattermost Web. It keeps Mattermost as the primary interface for login, posting, editing, and threads, while giving you a dedicated side workspace for mentions, channels, direct messages, search results, and saved posts.
  
  The extension is designed for workflows where you need to watch multiple streams at once. You can keep important channels visible, review unread items and mentions, track search results, and scan saved posts without constantly switching views. It also includes layout saving, appearance controls, realtime updates, keyword highlighting, and a quick jump-to-latest control for day-to-day monitoring.
  
  Mattermost Deck does not replace the native Mattermost experience. It works as a companion workspace focused on visibility and monitoring, and it activates only on the Mattermost server you configure while reusing your existing browser session.
