Warn about duplicate tabs with a prominent overlay and let you inject CSS to tune the page appearance when URLs match your rules.

概要 - Duplicate Tab Sentinel は、指定した正規表現にマッチするタブが複数開かれた瞬間に全ての該当タブへ警告オーバーレイを表示し、見落としを防ぎます。 - オーバーレイは視認性の高いデザインで、重複タブ数を即時に表示。不要なタブを閉じる判断をサポートします。 - ポップアップの簡潔な設定画面から、監視対象のURLパターンや正規表現フラグ、さらに任意のカスタムCSSを保存し、警告時の見た目を自由に微調整できます。 - すべての動作はローカルで完結し、Chrome の storage/tabs/scripting 権限のみを利用する最小構成です。 メリット - 重複タブを素早く検知し、作業の重複やリソース無駄遣いを抑制。 - カスタムCSSでオーバーレイのスタイルや対象ページの見た目を調整でき、ワークフローやブランドに合わせた運用が可能。 - 正規表現ベースの柔軟なマッチングにより、特定プロジェクトやサービスのURLにピンポイントで適用。 - 自動テスト付きで検証済み(ユニット+E2E)、信頼性の高い挙動が保証されています。
