[update]
Now compatibile for Firefox + Greasemonkey. Minor fixes.
[bug]
[todo]
/live 待機ページで左サイドバーが常時表示化されてる？自然と直った？
右側に表示されるチャプター一覧にも対応してほしいらしいね
https://greasyfork.org/ja/scripts/394945-youtube-live-filled-up-view/discussions/64579
Maybe I'll modify the script as below:
- normal mode with chat for keeping current "Filled Up View"
- normal mode with chat closed for (meaningless) YouTube's default
- theater mode with chat for "Filled Up View" with no distracting elements.
- theater mode with chat closed for "Filled Up View" with neither distracting elements nor chats.
コメ欄の比率カスタマイズ (greasyforkでの要望)
ついでにフォントサイズ、アイコンの有無、余白なども？
上部ヘッダをマウスオーバーでのみとかなんとか、なんらかの対処はしたい
チャットを非表示もXボタン化してヘッダ右上に
[possible]
[research]
ヘッダを隠す方法
LIVEに限らずBigTubeの代替を目指すか
上部マウスホバーで出現、スクロール上端からさらに上にスクロールでもx秒出現、下スクロールで出現、くらいかな
動画上部とカチャッと上部のコントロール要素をクリックできない問題は回避しなければならない
あくまでスクロー位置で調整することにして、多少の前後は自動スクロールでカバーするとか
きほんシアターモードへの移行でスクロール位置調整
むしろ本来的にヘッダを隠すのはシアターモードだけでいいよね
スクロールイベントで3秒表示という手段
https://greasyfork.org/ja/scripts/414234-youtube-auto-hide-header
infoの高さが変わりうるwindow.onresizeに対応か(パフォーマンスはスロットルすれば平気か)
[memo]
ダークモードはそれ用のユーザースタイルに任せるべき。
YouTubeのヘッダが常時表示なのはちょっと気にかかるが、高さにはまだ余裕がある。
