[update]
Minor fix for YouTube's update.

[bug]

[to do]
定期: 自動取得機能してるか
自分のアイコン内のメニューにあることを示唆するために ratingbars パネルを閉じる際は右上に向けて隠す
スクリプトの説明で設定ボタンの場所をわかりやすく説明とかスクショとか

[possible]
title属性に実数を入れる手もある?

[to research]
スクロールとリサイズだけトリガにして毎秒の処理を軽減する手もあるか
全部にバーを付与した上で中身の幅だけを更新する手も
  URL変わるたびに中身を一度0幅にすれば更新時のアニメーションも不自然ではないか

[memo]
要素はとことん再利用されるので注意。

各自にAPIキーを取得してもらっているようだ。他の拡張は全滅の様相。
