  [update]
  本日のアベマの仕様変更に対応しました。

  [to do]
  番組開始直後のコメントにセレクタが付かないので一瞬レイアウトが崩れるううう。

  累計500バグが解消されてるかどうか随時確認。

  timeを活用して自然に流せるか確認。

  通知を受け取るボタン
    z-indexどうにもならんのかな…
      最悪左に移しちゃえばいいのかな>>ナビゲーション要素は右側に統一されてる
    番組開始後も取り残されることがある?
    > 番宣CM中に通知を受け取るをクリックしても次に同じCMがあったときにまたボタンが出てくるのって前からだった? 

  パフォーマンス
    結局テキストトランジションなら軽い可能性?
      テキストならscaleが効く
      -webkit-text-strokeが使えるっぽい
      そこまでやるならiframeも復活だろうか>>せめてbody直下がよいみたい
    コメントペインの背景用divを挿入してopacity制御にすれば…?
      同じレイヤーにしないと非効率。

  番組表と通知
    完成したら裏番組一覧のスクリーンショットはコメント一覧を重ねない&秒前なし&やや切り詰め&縁取り太め設定のものに差し替えか。
    ついでに設定パネルのも差し替え。NGのも公式ブロック表示させつつ。
    アドオン拡張化
      Qiitaで解説

  [possible]
  4:3の時にずらせる?
  greasemonkey 4 系対応
  ユーザーブロックアイコンのアニメーション
  「お試しNGワードのハイライト機能は、注目したいキーワードを含むコメントにも活用できます。」

  [requests]
  設定のナビゲーションに「マウスを近づけたら表示する」
  設定のスクロールコメントに「画面下部の専用領域に流す」「高さ(%)」
  設定の一覧コメントに「コメントをひとつずつ表示する」

  [not to do]
  新着コメント緑ボタン後の表示は現状簡単にはアニメーションさせられない
  設定のスクロールコメントに「フォント」<<Canvasベースラインの問題があるので厳しそう
