Focus is a free Chrome add-on designed to minimize distractions while using YouTube. It allows users to cover parts of the YouTube interface other than the video player, ensuring that the viewer's attention remains on the content. The add-on also features a convenient pause function that automatically stops playback when users switch tabs, promoting a more focused viewing experience. This is particularly useful for those who multitask or need to juggle multiple applications while watching videos.

One of the standout features of Focus is its ability to resize the video player. By using the keyboard shortcut 'Ctrl + Shift + Z', users can reduce the size of the video player, enabling them to watch content alongside other applications seamlessly. This functionality caters to users who prefer a more integrated viewing experience, allowing for effective multitasking without losing track of the video.
