[update] 2.15.3
映像の背景色を黒(#000000)に。Chromeでのフルスクリーンバグを解消。

[bug]
[i]のときコメと視聴数

[to do]
windowフォーカス時にコメント欄フォーカスならハイライトしてあげる
マウスオーバー時の透過率設定
  Command+ホイールでコメント透明度はどうじゃろ?
  [1]-[0]で透明度はやるか
マウスオーバー時の透過率変化に対応する?
タイムシフトでのコメント対応(プレミアム限定?)
ビデオでもナビゲーションの透明化対応?
[i]の透明度は映像にコメ一覧を重ねない場合もっと濃くてもいい。重ねる場合もかな?
VideoAssistantとの統合?
NG設定ラベル [お試し] => [注目]

[to research]
投稿直後に出てしまう新着コメントボタンは1秒後に閉じてもいいよね
ブロックやNGでのコメント一覧スクロール位置
コメントが大量で一斉に流れてしまうときに、空白時間にもコメをばらけさせる?
まれにコメント取得できずにローディングが続くバグが(どこかでループしてる?)
気軽な「阿久津」「あっくん」のハイライトができるUXを
自分の投稿コメ+隣接1コメが一覧最上部に居残り続ける問題。
  タブ切り替えた瞬間に緑コメとして現れる。
  タブ切り替えで一瞬現れる。削除対象から漏れてずっと放置されている風。
  visibilitychangeの処理を再検証か。
  500と関係ある...?
  display:noneか何かでお茶を濁せないか

[possible]
NGワードの最終ヒット日時の記録(viaニコニコ)
ユーザーブロックアイコン(秒数と差し替わる)のアニメーション
ピクチャインピクチャはアベマが公式にやるべきだろうけど、やらないままブラウザが任意要素に対応したら実装しようか

[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」
一覧コメントの横幅「%」以外も指定可能に

[not to do]
Safari音量ボタンうわずってる件
4:3対応(左右黒帯の 16:9 video。videoの内容はDRM制限で取得できない番組あり。サムネイルの内容はcrossoriginで取得できない)
