YouTube Zoom Controller

Adjust the zoom and position of YouTube videos.

YouTube Zoom Controller adds practical zoom and position controls directly to the YouTube player. Resize a video, move it into a more comfortable viewing position, and return to your favorite layout whenever you need it. Key features: - On-player zoom control in the YouTube control bar - Resize and move videos in normal and fullscreen modes - Save and apply up to three layout presets - Optional caption placement below a moved or resized video when there is enough empty space - Automatically save your zoom, position, preset, and caption-placement preferences - Korean and English interface support, following Chrome's language by default - Optional logout guard for the YouTube account menu Keyboard shortcuts: - Shift + Arrow Keys: Move the video - Shift + +: Zoom in - Shift + -: Zoom out - Shift + 1: Restore the default layout (100%, X 0 / Y 0) - Shift + 2 to Shift + 4: Apply saved layout presets - Shift + Backspace: Reset zoom to 100% - Shift + Delete: Reset the video position Notes: - Caption placement is optional. It returns to YouTube's original caption position if there is not enough safe space below the video. - Layout presets do not change the caption-placement toggle; it stays on until you turn it off. - The extension works only on YouTube pages and requests access only for youtube.com. What's new in 1.0.4: - Improved playback performance by limiting layout and caption updates to relevant player changes. - Improved caption placement stability when player controls appear or disappear. - Improved the optional logout guard so it detects the account menu after it opens.
