When you start watching a YouTube video, the thumbnail that caught your attention disappears. Ever clicked on an eye-catching thumbnail, only to find that… The video takes forever to get to the point. The content isn't quite what the thumbnail made you expect. You've opened several videos in different tabs and forgotten which thumbnail caught your eye. The video feels a little thin, and you want to take another look at the thumbnail. Now Watching Thumbnail keeps the thumbnail of the video you're watching visible at the top of the sidebar, so you can compare it with the content as you watch. It doesn't tell you whether a thumbnail is misleading. It simply gives you the chance to decide for yourself. If you've ever thought, "Wait… why did I click this again?", this extension might be for you. Simple, lightweight, and ready to use. ------ いま視聴している動画のサムネを、横に表示してくれます。 ・サムネで気になってクリックしたのに、肝心の内容がなかなか始まらない…… ・そもそも、なんでこの動画を見たいと思ったんだっけ? ・先にいくつかの動画をタブで開いたので、どのサムネが気になったのかわからない ・内容がちょっと薄い……もう一度サムネを確認したい Now Watching Thumbnail は、いま見ている動画のサムネをサイドバー上部に表示します。 サムネと実際の動画を見比べながら、自分自身で判断するためのちょっとした材料としてお使いください。 つねづね「ちょっとサムネをもう一回みせて!」と思っていた自分と、同じように感じているあなたのお役に立つかもしれません。 インストールするだけでOK、そのまま使えます。
